I posted the workaround that Shriramana commented on in Kubuntuforums. It worked on my Foxconn 915M12-GL-6ls motherboard (Intel 915GL based) desktop running Kubuntu 11.04 with the 2.6.38-8-generic kernel and Xorg 2:1.10.1-1ubuntu1.1 dated 21 May 2011. The Foxconn MB uses an 82915G/GV/910GL on board integrated graphics controller for video display. Sorry to hear that the workaround doesn't work for all... Hopefully there will be a fix forthcoming soon.

Cheers, Bill

Here's the original text of the workaround:
-----------------------------------------------------------
I booted to the 11.04 signon screen. Then did a ctl-alt-F1 to get a terminal window in Kubuntu (without logging on to KDE.) At this point, I went to the default directory (/etc/default) and modified grub2 file to boot as follows:

sudo nano /etc/default/grub

Change the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.modeset=0"

Then rebuild the grub.cfg file by running:

sudo grub-mkconfig --output=/boot/grub/grub.cfg

Once this is all done do a

sudo shutdown -r now

to reboot. At this point I was able to boot into the KDE graphical desktop signon screen and actually signon and get to the graphic desktop without kernel faulting.
