Log Message:
>From Julian Coleman:
- there are a couple of registers that are reset after the X server finishes,
which do not have the same values as they do when the machine is powered
on. If the two are mismatched you can't write to the video memory.
- video memory is mapped at offset 4MB to keep the X server happy
- there is now a VGA memory mapping
- DEBUG_ET4000 is now a bit more useful for debugging!
