Intel chips are not well supported on Fedora 9 and updates, applied today make things worse.
I have just updated two computers, both using intel chips, which are supposedly supported by the intel driver for X. On both machines (an x86 and an x86_64) X simply doesn't start up -- the symptoms are RHGB not starting and GDM erstarting all the time. On the x86 machine the VESA drivers work, with worse support than before the updates -- the supported resolutions are now 800x600 and 640x480, while it had support for 1024x768 before the updates. The x86_64 has the same symptoms using the VESA drivers as using the Intel drivers.
Be carefull when updating to the newest X and drivers.
