PCI HME/ISP cards are not rare at all... I've got one 
myself. NetBSD/sparc64 will almost certainly need one 
when PCI support is more fully implemented. Sun ships 
*lots* of those cards, especially in Ultra 5's and 10's 
which have no onboard SCSI bus. It's an easy way to get 
an external SCSI bus in the machine when shipped.
