Well, after much tracing etc., I finally figured out why the MacROM Glue 
code wasn't working on a Mac IIci.  Turns out that, at the very end of 
module macrom.c there's a little routine mrg_initadbintr that is supposed 
to enable the VIA1 interrupt for the ADB bus.  But, it was written so 
that it only set the enable bit if you were running on a plain old Mac II 
(or some other variants, like the SE/30);  the code doesn't execute on a 
IIci, or IIsi.

I hacked the routine to execute the enable-interrupt code on a system 
with current_Mac->class == MACH_CLASSIIci and it got all the way through 
the ADB init code with no errors.

Now, if I can get SUPped to current and get the grf.c fix, maybe I will 
really be running -current.
