To add one more very interesting piece of data,
booting a 2.6.32 32-bit kernel.org kernel in a PV
guest works, while booting a 32-bit
kernel.org kernel doesn't... same config file!
And the failure looks very similar to the one
I've been seeing on several x86_64 kernel.org

I'll confirm that I can reproduce this, and then
post as a separate thread.
