Yes. vader.toddpw.net has 2 USB ports. It likes the iMac keyboard just fine.

uhub1 at uhub0 port 2
uhub1: Alps Electric Hub in Apple USB Keyboard, class 9/0, rev 1.10/2.10, addr 2
uhub1: 3 ports with 2 removable, bus powered
ukbd0 at uhub1 port 1 configuration 1 interface 0
ukbd0: Alps Electric Apple USB Keyboard, rev 1.10/1.02, addr 3, iclass 3/1
wskbd1 at ukbd0 mux 1
wskbd1: connecting to wsdisplay0

The iMac and pckbd keyboards mux together happily and I can switch between
them in the same console session, including virtual terminal switching (use
'option' for Alt).

Last night's time-travelling was inconclusive -- but sometime around mid-may
(same time as the "glue" cleanup) appears to be when the 'dead keyboard'
symptoms start. I don't have enough sample points and I really have to move
on to the distrib/ unification so I'm just going to keep the iMac at 1.4.3_*
for now, and use that to develop pre-backported changes (plus the iMac is
the fastest of my scratch machines).
