I just tried kernel-2.6.32.10-1.2.92.xendom0.fc12.x86_64 from Mike Young's repository on my MacBook and found that the video driver does not seem to work. Lspci reports:
02:00.0 VGA compatible controller: nVidia Corporation GeForce 9400M (rev b1)
The system boots fine until X is supposed to start. Once this happens, the console freezes. Otherwise, the system continues to operate and respond to network traffic.
The last thing I seen in Xorg.0.log is "(II) NOUVEAU(0): Opened GPU channel 2." In a *working* configuration, the next message logged is "(II) NOUVEAU(0): [DRI2] Setup complete."
There seems to be some related work here:

I have seen that other people are having some video problems and wanted to add my own (on the mailing list until we are in Rawhide / Bugzilla).

Have previous versions of the xendom0 kernels worked successfully?

What is the grub.conf entry? Have you passed nomodeset to the kernel module?

Yes. However, I have been away from Xen for a few months. I have lost track of which kernel I was using before. I know that it worked fine on my graphics card with no changes to the default (non-Xen) configuration.

I tried adding nomodeset, but that did not help by itself. I ended up doing the following:
1. Add nomodeset to kernel command line.
2. Create an xorg.conf that uses the VESA driver (X -configure, edit).
3. Deactivate dri2 and dri in xorg.conf.
4. Boot Xen Dom0 kernel into runlevel 3.
5. rmmod nouveau; init 5.
This works (of course, the VESA driver is not optimal).

In the past I have had success using nomodeset followed by either "video=vesafb" or "vga=XXX" for a vesa mode. These have the advantage (if they work) of (a) not changing the basic config so a better driver can be easily tested, and (b) being easily by boot line edit tested before making any changes which need file edits.
Deactivate dri2 and dri in xorg.conf.
Boot Xen Dom0 kernel into runlevel 3.
rmmod nouveau; init 5.

I was able to simplify this a bit:
1. Add nomodeset to kernel command line.
2. Remove all xorg video drivers except the VESA driver.
3. Add "blacklist nouveau" to /etc/modprobe.d/blacklist-nouveau.conf.
4. Run "dracut --force" to rebuild initramfs with new blacklist entry.
This avoids the requirement for a hard-coded xorg.conf. I previously had trouble keeping the nouveau module from loading. I had forgotten that it is necessary to rebuild an initramfs to ensure the system does not load blacklisted modules.
Kernel been built on branch xen/stable-2.6.32.x checked out via JF's Git Repo does work with DRM enabled under Xen 4.0-rc7 on F12. (Radeon HD 4650). Appears to be 2.6.32.10 in meantime. How much sense does make using rpm's based kernel with "nomodeset" option ?
