This can be done using the environment and appending ::r (?) after the driver specs, IIRC.
Indeed with
set GRX20DRV=VESA::R gw 1024 gh 768 nc 16
the various programs launched by demogrx work while without the ::R they fail as described previously.
So it´s either a problem with the GRX pm banking code or with the ATI bios pm banking code. If its a problem with the bios, we could try to auto detect the problem after mode setup in PM banking mode and fall back to real mode banking ...
Please use ::B to force banking instead of linear framebuffer and check if the 8bpp modes and up still work. If they fail try ::BR ...
