Drat. Could you try the patch at 
http://people.freebsd.org/~nwhitehorn/adb-delayed-attach.diff?

I'd also be interested to know what the bit of your dmesg around 
macgpio0 looks like, in particular the line from the attachment for 
pmuextint0. Unfortunately, ams0's attach doesn't have any debug 
information in it. It is stuck somewhere between lines 171 and 183 of 
adb_mouse.c, if you want to fill it with printf().
