IIRC all PCI slots in the PWS are behind a PCI-PCI bridge that 
hides the Pyxis DMA bug. 
Ups, no. The 64 bit slots are on the primary PCI bus.

On the other side: How many 64-bit PCI cards do you have and do you 
really need it? I would have to look at the bus_dma(9) routines of 
NetBSD/alpha to confirm this, but I have somthing in the back of my
head that NetBSD/alpha has a work around for the Pyxis DMA bug.
