Outside of the changes noted in the Ultrix 2.0 Release Notes - 
removing the BIF_SST bit from the bisw and device driver probe routines
no longer using their own br and cvec - what are other changes necessary to
make device drivers which worked under 1.2 work under 2.0?  I have a tm11
which will not interrupt.  The probe finds that the device registers are
there but the device simply will not interrupt.  I also have a dr11 which
will interrupt but you cannot otherwise use the device.

Any suggestions are greatly appreciated - it's not obvious what the problem
is.
