Good question. I can see that 7.4 supports GEM but I see nothing about
kernel modesetting (
http://www.phoronix.com/scan.php?page=article&item=xorg_74_final&num=1).
I know it's enabled in the Fedora (since Fedora 9) xorgs but I have no
idea about openSUSE (which I believe is what you are using based on
package numbers). Apparently kernel modesetting can be turned off on the
kernel command line by using nomodesetting so that might be a quick
thing to try...
