Yes: you must say

	config	vmunix		root on ra0 swap on ra0 and ra4

(Personally, I prefer to be explicit: `config vmunix root ra0a swap
ra0b and ra4b args ra0b dumps ra0b'.  The above is equivalent, though.)

It does (although there is an, er, `interesting' bug when the
d_psize routine is unimplemented).

Just a bug.  Fixed in the new driver in the forthcoming 4.3-tahoe.
The old driver is full of mysterious bugs.  In particular, a number
of people claim it tends to hang when using multiple controllers on
a uVax II.  (I have had one or two reports that my rewritten driver
also hangs, and one that it fixes the problem.  Which is right I
cannot say.)
