+ Removing bootsplash support since it hasn't been in a kernel we've supported
+ for years now, causes confusion amongst users, and really wasn't being used
+ and caused issues with 2.6/initrd creation in some corner cases.

-pkg/genkernel-svn-suspend.patch:
Removing the reversal patch for the suspend removal, since it will no longer
IMPORTANT KERNEL NOTES:
- You MUST have /dev/pts turned on.
- - If you want Bootsplash, you MUST have VESAFB enabled for 2.6,
- other framebuffers won't work. You MUST also enable
- "video mode selection support" and "Framebuffer Console support"
- - From gentoo-dev-sources-2.6.8 and above, bootsplash has been replaced
- with gensplash. Gensplash has the same kernel configuration requirements
- as bootsplash, but works properly with any framebuffer device.
- - To build a kernel with Genkernel you must have
"Block devices->Loopback device support"
"Block devices->RAM disk support"
- To boot genkernel properly, the kernel config must have
root= needs to point to the ramdisk (should stay at /dev/ram0)
init= needs to point to the linuxrc file to execute on the ramdisk
vga= should be the resolution you want your screen. 0x317 is
- 1024x768 - 16bpp and you'll get a pretty bootsplash if
+ 1024x768 - 16bpp and you'll get a pretty splash if
configured properly

All that is needed to run genkernel is just ``genkernel'' with an action
and any flags you might need:
.PP
-# genkernel --menuconfig --no-clean --no-install --bootsplash all
+# genkernel --menuconfig --no-clean --no-install all
.PP
This would produce a kernel, asking you what how to configure it
-to your desire, leaving alone any existing compiled object files, enabling
-bootsplash support but not installing anything.

.SH ACTIONS
An action tells genkernel what you want it to do - the following
actions are supported:
.PP
.BR Initialization
.TP
-\fB\-\-\fR[no\-]\fBbootsplash=\fR<theme>
-If the extra argument is specified, bootsplash is forced using <theme>
-rather than the default theme specified in your bootsplash
-configuration. If \fB\-\-no-bootsplash\fR is specified, then
-bootsplash is disabled.
-.TP
\fB\-\-\fR[no\-]\fBgensplash=\fR<theme>
If the extra argument is specified, gensplash is forced using <theme>
rather than the default theme specified in your gensplash
.TP
\fB\-\-initramfs\-overlay=\fR<dir>
Directory structure to inject into the initramfs.
-Only available on 2.6 kernels that don't use bootsplash; use a CPIO
-archive as a parameter.

The following options can be passed as kernel parameters from the
bootloader, which the initrd scripts would recognize.

-# Copy bootsplash into the initrd image?
-BOOTSPLASH="yes"
