go back to the xpert98.  or buy an nvidia card.
seriously.  i hate the mach64 series.
they're awful to program.

but if you're hell-bent on using it...

let's assume you can boot without vga
and compile a kernel.  (to boot without
vga log in as none during the boot sequence.)

there is a call:

	init_overlayclock(scr);

in /sys/src/9/pc/vgamach64xx.c.  
comment it out.  i think that will
make your problem go away.
