[9fans] More Mach64 Problems

[Cameron Morland <cjmorlan@uwaterloo.ca>]

Hello,

I managed to acquire a Mach64 Rage II PCI card, which appears to be
supported. Using a new download, I get

aux/vga: controller not in /lib/vgadb

Searching in vgadb, I find

        0xC00E1="MACH64GTPCIUYMU"                       # ATI Rage II PCI

Which has the wrong offset, but the right string. So I replaced the
0xC00E1 with 0xC00EA. Now I get a video signal, but instead of being
the entire screen it is the first 1/3 of the screen, repeated 3
times. The mouse moves over the whole screen (due to the hardware
cursor). I've tried some adjustment to the monitor size and type, but
no changes were apparent. (I'm running at 640x480x8 right now.)

Actually it's not exactly the first 1/3. More precise would be:

0123 4567 89AB CDEF

turns into

0123 4012 3451 2345

ie the three bands are slightly different.

Suggestions?
