There really aren't that many BI-bus VAXen. The 6000s, for example, only use
BI for I/O. And between the XMI-BI adapter and the BI-UNIBUS adapter, the
performance out there in UNIBUS-land gets pretty poor. UNIBUS isn't even
supported on the high-end machines. What little news I've been getting 
about the Alpha machines looks discouraging for CSR accesses in general,
let alone talking to EISA registers.
