I just got loaned a vr260 and have not had a lot of luck with it.  Although
I was able to get a kernel built that would recognize its existence as the
system console, the TK50 drive no longer works.  When I boot the previous
kernel (which displays partly on the vr260 & partly on the vt100 as the
system console) everything works fine (no vr260, but I do get a TK50).  I
don't touch any hardware, just change the kernel.

Here's the line I added, straight from the GENERIC conf file.
	device	qv0	at uba0	csr 0177200 flags 0x0f vector qvkint qvvint

I've tried moving the physical location of the boards around in the
backplane with the same negative results.

Any thoughts?  (This is Virginia where this type of cohabitation may still
be against the blue laws... :-) )  Thanks.
