Look at the very e-mail of this thread. He had dom0 and domU using the 
same address for the kernel.

Anyway, regardless what Denis reported, there are clearly an issue if 
Dom0 and Dom1 kernel are using the exact same loading address and the 
kernel is compressed. This would be fairly easy to reproduce.
