Did the 32 bit mode use to work, before I made this patch? And what
happens with the VESA driver in the 8, 15 and 16 bit 640x480
resolutions?

Yeah. At the moment, Allegro only supports truecolor resolutions via the
VESA driver: none of the register level hardware drivers can do this.
I'm planning to start working on direct support for different color
depths as soon as 3.0 is released, but that isn't going to happen within
the next few weeks.

I think you are getting confused about what each of these patches is
supposed to fix :-) The ATI driver patch should make the GFX_MACH64
driver work in the normal 256 color SVGA resolutions. This new version
of the VESA driver might help some of the people who were having trouble
accessing hicolor modes via the GFX_VESA* drivers, but it won't make any
difference to the Mach64 code...
