I've noticed this too, on my 660av using internal video. I think the
problem is that in itematch():
pa = pmap_extract(pmap_kernel(), (vm_offset_t)(gm->fbbase + gm->fboff));
return (pa == (vm_offset_t)m68k_trunc_page(mac68k_vidphys));
gm->fbbase is the framebuffer address rounded down to a page boundary, and
gm->fboff is the offset from the page. This is being compared to
mac68k_vidphys rounded down to a page boundary, which isn't going to work
if fboff is non-zero. In my case, fbbase is 0x50100000 and fboff is 0x100.
