I believe you can do this:

        When you see the GRUB spash screen on boot, press a key.  Select
        the top kernel line of the options offered and type 'e', select
        the kernel line and type 'e'.  Append 'video=vesa' at the end of
        the line.  Type [Enter], type 'b'.

Then X should detect your video card as vesa, which is the most generic
sort of interface.

If the machine boots, you can boot in runlevel 3 (edit the kernel line
in GRUB as above, but instead of "video=vesa" add "3".  Then you'll get
a virtual console to log into.  Then (as root) run

	system-config-display --reconfig

and see if that helps.
