Interesting. This might turn out just to be a differnce in kernel config
between the xen and native kernels you've tried. It might be interesting
to compile up a stock 2.6.11.10 native kernel with a config as close as
possible to the xen0 one, and see if the same problem is exhibited. 

Also, if there are any USB options in the BIOS (e.g. legacy support) it
might be interesting to know if they have any effect.

It would be particularly interesting to know what the unstable tree does
on these systems, as the code is quite different.

Best,
Ian
