Ive thought about it some, and I recall you defined your supported
horizontal sync rates explicitly, rather than in ranges.
Say you have support for a 35.1KHz sync. Try replacing that with
support for a range of 34.7KHz to 35.5Khz. X may be rejecting
modelines because the horizontal rate isnt correct.
As root, from console, with no X running, do the following:
X &> X-Output.txt & sleep 60 ; sync ; kill `ps a | grep -v grep | grep
X`
Examine X-Output.txt after a minute or so has gone by (or for the
impatient, use ctrl-alt-f1 to get back to text). The reason for
modelines being rejected should be listed in plaintext english.
