this depends on your monitor and your exact nv chip.
i have a syncmaster 204b and a
1.0.0:	vid  03.00.00 10de/01d3  10 0:fd000000 16777216 1:f000000c 134217728 2:00000000 16 3:fc000004 16777216 4:00000000 16
this chip doesn't work at all without some modifications,
which are likely always correct.  but the timing is still off;
the monitor doesn't sync when the chip is given the
correct timings.  i don't have an oscilliscope handy, so
i don't know if the timing is correct and the monitor
can't handle it or what.  and i don't remember which
changes have to do with timing anymore.

i attached my hacked-up copy.  nv almost always goes off
into the weeds if given a bad timing.  so you might
not want to do this on your fileserver.

i'd probablly start with some of the register fixups; i'd
try not to mess with the clock unless i had to.
