The core problem is that the real-mode emulation in Xen is broken, so its not handling the switches between 16&32bit mode correctly. We tried to fix Xen but the VMX assist code is just tooo hairly to resolve correctly - a fix for one graphics card would break a different one. So instead, our Xorg wizards have patched the X server to use its own built in realmode emulation instead of relying on Xen. The updated 'xorg-x11-server' RPMs are being prepared for a Fedora Core 6 update in the very near future, so keep an eye on the updates-testing YUM repository for the fix....
