Can't get uba1 to work w/750 under 4.2

[Chris Torek]

Does the 4.2 distribution have a preallocated UBA1 interrupt vector
area?  If not, that's the problem.  If you look at ubavar.c (and I
think locore.s) you'll find a ``UNIvec'' table.  This is used for UBA 0
interrupt vectors.  Unfortunately for Comet users, the scheme used to
allocate interrupt vectors for UBAs 1 on up doesn't work on 750s.  So
autoconf and locore.s and so forth need to use one allocated in ``low
core'' like UNIvec.

(I don't have any more specific information; this is what I remember
from a fix posted long ago for 4.1.)
