Pascal,

	Thank you for taking the time to help. I'm really stumped here. The funny 
thing is "Yes", even with all vga= lines removed, I get native resolution of 
what looks like 1280x1024 when the box boot. What happens is the box will boot 
and the first 20 or so lines is in 640x480, then magically the box switches to 
1280x1024. The actual resolution of the monitor is 1680x1050 when X starts 
(well when it used to start). I have never had this much trouble with X 
before.

	In answer to your second question "Yes" I have booted to runlevel 3 and tried 
to use startx -- same result. X tries to start then crashes. Here are some 
more hardware details in case that would help. The box is a dell gx280 with a 
P4-3.2GHz processor. The output of lspci is:
