X doesn't work after upgrade to RH9

["Schuyler, Peter" <Peter_Schuyler sra com>]

To All,
I just upgraded my Dell Latitude C800 from RH7.2 to RH9. While the
upgrade appeared to have gone perfectly, when I rebooted X won't
startup, yielding an error of "no screens found". The laptop has
an ATI Rage 128 Mobility M4 card. I've gone through and looked at the
XF86Config-4 (see below) and compared it with the rpmsave version,
and the two are largely the same, but 7.2 worked fine.

For what it's worth, I used the graphical install, and everything
worked fine. Anyone have insights on this?
