	Might have missed something, I wasn't particularly clear about all of my 
kludges..  =)  Don't know if there's a better way, but try an "nm -no netbsd | 
grep 0015" and see what function 15c300 would be in?  The "swapper" seems 
bogus, I sit at the same instruction (the lwz) in "Debugger" (which makes a 
lot more sense) when my kernels die.

	Yeah, GDB (or whatever we use in the kernel) is currently broken on the 
PowerPC's as I understand it.  Doesn't really hurt me much, I know very little 
about GDB, and tend to take the approach of many printfs/recompiles (and 
nm|grep's) to see what's going on..  =)

>Oh, and I don't think it found a wd0, even though it did find the cd0.

	That's correct.  Since the CMD PCI0640 controller was "not configured", it 
was unable to find wd0.  cd0 (and sd0 if you have a Zip drive) are off of 
Paddington's internal IDE controller, which is detected with some changes, but 
still does not work (it seems that most interrupts are not getting through the 
bridge, it's why bm0 is sending but not receiving, and when I tried booting 
off a zip I got lost interrupts and lots of timeouts (the drive was never 
accessed).  It's not everything, as USB seems to work just fine.  But it seems 
that at least interrupts from Paddington aren't making it through the bridge, 
at least that's my guess on things.  Would the Paddington IDE drive detection 
work without interrupts, or is that proof that it works at least some of the 
time?).  As far as the CMD controller goes I'm going to give a shot at porting 
pciide to macppc, it seems like it should be fairly easy, when I tried this 
past weekend it seemed that at least the iot's were getting filled out 
incorrectly upon entry to the pciide routines.  Will take a closer look at 
things, probably not until this coming weekend, though (really don't have time 
to code during the week).

	Yes:  "shut-down" (if power-off does what I'd imagine it does..  =)
