Yeah I have just checked this against my machine and the PBA version is
D13607-804 (higher than the required). So it should be fine.

I have just upgraded the Hypervisor to 3.1.1 (backported from Debian
lenny). And the problem still exists but in a slightly different form.

The full complement of processors still fails to work all the time but
it doesn't bail out in such a horrible way:
(XEN) Booting processor 7/7 eip 90000
(XEN) Not responding.
(XEN) Inquiring remote APIC #7...
(XEN) ... APIC #7 ID: failed
(XEN) ... APIC #7 VERSION: failed
(XEN) ... APIC #7 SPIV: failed
(XEN) Unmapping cpu 7 from all nodes
(XEN) CPU #7 not responding - cannot use it.
(XEN) Total of 7 processors activated.
(There is meant to be 8 of course)
(And carries on to boot)

I wonder if other people are experiencing this problem and just not
realizing it?

Anyone have any bright ideas? :)
