Does it give, by any chance, this message?
xf86MapVidMem: could not mmap /dev/vga (Invalid argument)
This happens to me (I posted this on the port-i386 list, since it is
an i386 problem), and 2 other people said they had this problem as well.
I vaguely remember a message on a list somewhere a while ago that mmap
now does a stricter argument checking. I think it was with MAP_FIXED
and the address not being on a page boundary. Maybe this is the
problem.. but I don't have the XFree86 sources here, so I can't tell what
it is doing. A ktrace did tell me that the EINVAL comes from mmap().
