PATCH_VER 0.3.1. This should help out PPC users on Radeon and Rage128.

(fd.o #2064) Add 5160_all_6.8.1-benh-radeon-ppc-fixes.patch, with tons of
changes:

1. This patch adds the "VGAAccess" option (defaults to NO on PPC and YES on
others) that disables all legacy VGA stuffs in the driver, since they are
causing various issues on non-x86 machines.

2. This patch makes sure CRTC2_OFFSET_CNTL is cleared. None of the options in
this register should be enabled with our current driver, and some firmwares
setup a tiled display, which we _must_ disable for now. Without this, the
second screen is completely scrambled on some PowerMacs.

3. This patch fix the routine that probes for PLL values in absence of a
BIOS ROM. The measure is more precise, done several times to avoid
"gliches" caused by scheduling latencies, plus the patch fixes actual
bugs in the previous iteration of the code. It also add calculation of
the mclk and sclk values for proper display bandwidth calculation and
adds proper min/max PLL values for r420 type cards.

4. The display bandwidth calculation code has a small bug when looking at
the memory controller setup on r300 chips. Hui from ATI confirmed that
this was the right fix.

5. When using MergedFB, the driver would call RADEONInitPLLRegisters for the
first head even when UseBiosDividers was set to TRUE, which was incorrect.
This patch fixes it by moving the test of UseBiosDividers into
RADEONInitPLLRegisters which simplifies the code in the caller and is more
logical.

6. The dual head setup was recently re-broken (after having been fixed a while
ago) with SURFACE_CNTL beeing written with the wrong value from the second
head. The problem is that usually, only the first head had a correct value
in there, and the driver would regular mixup which register setup was used to
restore that value. This patch fixes it once for all by making sure the
second head does carry the proper value too.

7. The second digital output of the radeon chip doesn't like when the P2PLL
is set with an odd post-divider value. This makes sure we never chose
a "wrong" value when calculating the P2PLL setting on a non-CRT screen.

8. On some cards where no BIOS provided output mapping infos is available, the
driver would get the DDC flipped between the two outputs of the card. This
typically happen on recent Mac cards. This adds an option to force the
driver to reverse what it thinks is the primary display DDC and the
secondary display DDC. Ultimately, we'll have to do a better job of
recognizing those Mac cards though.

9. RadeonValidateFPModes() has a bug where it could try to dereference
a NULL pointer in some cases when linking in modes. This fixes it.

10. This patch adds an option for probing the PLL value at server init time
for LVDS panels and re-using it later (by setting UseBiosDividers). It's
useful on machines without an X86 BIOS image providing the proper set of
divider values for the LVDS, as the value calculated by
RADEONInitPLLRegisters() tend not to be suitable for some LVDS panels.
It also changes a bit the way the panel infos are extracted, the previous
code didn't quite work for me, and after discussing with Hui, I decided
to move the detection earlier in the discovery process and to do it slightly
differently.

(fd.o #2089) Add 5135_all_6.8.1-r128-ppc-vgaaccess.patch. This patch adds the
"VGAAccess" option (defaults to NO on PPC and YES on others) that disables
all legacy VGA stuffs in the driver, since they are causing various issues on
non-x86 machines.
