It appears that I haven't updated from sources in a while.
I pulled today and found on reboot that my screen just
went black going into graphics mode.  I recompiled aux/vga
with different versions of i81x.c and both versions after
Aug 28 act "funny".  I'm pretty sure it has to do with
the new code to set refresh rates for a CRT.  Comments
in the source seem to indicate that some LCD stuff is on
the TODO list.  I guess that might mean this is a known
problem.  I don't have time to fix it myself now, though,
so I'm posting here.  In the meanwhile, I'm just using
the Feb 17 version of i81x.c.

Probably, it was my fault.
David Hogan assumed that all the registers are properly
set by the BIOS, however, what means all is not so clear
to me.   I left most of those value untatched.  But I have
no convinsed it's just enough.

Please let me know (personally, I prefer) the values of registes which
aux/vga -p <1024x768x8> command reports.   The resolution
should be replaced by yours.   This may help me.   Another person
is also facing the same problem

I forgot one sentence.

Please send me the two cases, one is the result of older
driver, and the other is that of new unwork result.
