Aha, I guess I was mistaken about the SRM and IDE support in the various
versions... I do distinctly remember there being stupidity like that
at some point, however :-)

As to why NetBSD called it "wd0a" .. NetBSD, by default, assigns unit numbers
as it finds devices, and doens't have any default mapping from unit number
to physical location of the device.
