Well I just booted a 1.5AZ kernel and it didn't seem to like it
all that much.  I'll tell you more after I get it installed.

Any chance I can convince you to look at what we did wrong in FreeBSD
wrt to USB?  Printing seems really broken, in fact 'cat /dev/ulpt0'
under -stable causes a hang when and a crash under -current when
cat ternimates and the device node is closed.

We die in uhci_remove_bulk, things like umass seems to work ok though..

anyhow I'm rambling, I'll let you know what I find out after my
install completes and I try to port over my work from freebsd 
to netbsd to get this damn stuff working...
