same card is working ok with X Windows. bandwidths are supperted (ramdac
is 170MHz), i have fast edo dram on it. i just cannot imagine where the
problem could be. yesterday i started comparison of
/sys/src/cmd/aux/vga/virge.c (resp. parts of the kernel) and source of
the S3 ViRGE driver in XF86_SVGA server and still haven't found
problem...
