ati driver (fglrx) and no 3d acceleration

[Christopher J. Bottaro]

yes, that fixed the problem, thank you both.  one thing to note, after
changing that option, i had to reboot my machine, a simple restarting of X
didn't work.

hmm, i think this should be in fedorafaq.org's section about the ATI
drivers.

thanks again.
