Hmm. This might make oldcard work out of the box on my VAIO again.  The
video bios goes from 0xc0000 -> 0xd3fff (80K, not 64k).

But then again, XFree86 was still hosed last time I checked.  First, it
tried to copy the whole 80K rom into a 64K buffer and crashed.  Now, the
driver copies the first 64k only, and then tries to execute the bios under
x86emu (or whatever it is called).  This is not your problem though. :-)

Cheers,
-Peter
