...speaking of wacky cards...

I have 2 NetApp SCSI boards, and could loan you one, Matt.  They're
pretty straight-forward:

	- IBM 27-82351 PCI-PCI bridge
	- 2x Qlogic ISP1040B
	- PLX PCI9060ES
	- 2x Cypress CY7c1031

I'm guessing Cypress chips are general-purpose gate arrays (still have
to hunt down a databook for them), likely used for RAID parity computation
assist.  The PLX chip is probably the PCI glue and DMA controller for them.
Still need to hunt down that chip's databook, too.

However, in all likelihood, NetBSD should be able to drive the ISP1040Bs
as-is (assuming driver-supplied firmware; NetApp probably uses custom
firmware).

Note that conventional wisdom says that this board won't work in a PC,
because the IBM bridge confuses the hell out of the PC's firmware.  However,
I'm going to plop one into an AlphaStation this afternoon, for kicks, to
see what happens.
