X trouble with Intel xxx chipset in FC5T2

[Willem Riede]

I tried to upgrade an oldish Dell Optiplex GX110 that's now running FC3 to FC5T2,
and this is how far I got:

... Intel 82810E DC-133 cGC [Chipset Graphics Controller]
... Viewsonic P813
1...2...3...4...5.... X server started successfully
mini-wm: Fatal IO error 104 (Connection reset by peer) on Xserver :1.0

and the tail of X.log reads:

(EE) GARTInit: Unable to open /dev/agpgart (No such device)
(EE) I810(0): AGP GART support is not available.  Make sure your kernel has
        agpgart support or that the agpgart kernel module is loaded.
(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found

Known problem? Should I bugzilla? Provide more information?

Thnaks, Willem Riede.
