I think Rusty's xen share also had a similar problem caused by
the hypercall number conflict.
Xen/ia64 with virtual physical model also needs a hypercall number
for its own use.
Currently it large enough (=256) that it is unlikly to be used by xen/x86.

Is there any convension about how to take hypercall number?
At least hypercall numbers for arch-specific purpose and
experimental purpose should be defined.
