Well, 'nomodeset' I don't think will help b/c you don't have KMS in
squeeze (I believe so).

The other thing is that you have:
Aug 21 09:08:27 BUBBLE kernel: [    5.046676] NVRM: loading NVIDIA UNIX
x86_64 Kernel Module  173.14.25  Thu Jan 28 01:53:43 PST

the proprietary NVidia driver loaded. We haven't tried those
yet and instead focused on making sure the upstream nouveau drivers
work with Xen. Which they do now.

I would suggest you boot in runlevel 3, so that X is not started and see
if the machine works (as in, you don't see other failures).

And if you want X and the NVidia driver (the proprietary one), you might
need to take the brunt of debugging it and finding where the NVidia is
doing some weird stuff.

Or, there is another option, and that to use a back-ported version of
2.6.34 DRM/KMS/TTM driversets which include the nouveau support.
(I am right now running with that on a GeForce 8600 GT on Xen 4.1 +
latest PVOPS kernel).
