update the list of supported cards

mite.c expects that the buffer is vmalloc()ed.  This might not
be the case with real-time.  The planned fix for this is to
no longer allow real-time applications to allocate their own
buffer.

comedi_rt_timer segfaults when the lower-level driver disappears
and reappears.  This is a problem with the Comedi core, not the
driver.
