FC4T2 xorg/matrox failure

[John Austin]

Hi,
    Having had problems with xorg/Matrox G550 on FC4T1
I was hoping for improvements at FC4T2 but ....
cannot use the graphics install as the screen is corrupt,
can't read the install notes even!!!!
After text install, reboot etc, startx from run level 3 fails with
corrupt screen, unusable and still totally corrupts virtual terms
Cont/Alt/F1-6
Reboot the only answer :-(

Anyone else with the same problem ?????
I will be adding this to bugzilla 
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=153729
and xorg bugs
