So we will be alright in x86_64 land once the upgrade to 2.6.13happens.
But there is still a problem in x86_32 land. The function pointer for
ioapic_renumber_irq() which is called by mp_register_gsi() is
initialized only on the ES7000. Dom0 is oblivious to the fact that itis
on the ES7000. How can we work around this problem?

Why does i386 need that hook, but not x86_64? Is it for legacy ES7000boxes?
