There is more sad stuff involved with drivers assuming IO ports fit in int. A proper fix for 2.6.23 will be the rework of PIO allocation I'm doing. A temporary fix for 2.6.22 would be for Olof to use reserve_phb_iospace() to make sure his PIO gets in the low 31 bits. We need to add a spinlock to it though.
