Not yet but has now:

The regression occurred between xorg-x11-drv-intel-2.6.99.902-2.fc11
(as seen on Fedora 11 Snapshot 1 LiveCD) and
xorg-x11-drv-intel-2.7.0-1.fc11. If I limit the update to just the
driver, the machine will boot but GDM and beyond has a very corrupted
screen. Each subsequent horizontal line has been shifted some offset
from the one before instead of being aligned.
