 I have seen this, too.  I tracked it down to ADB through the VIA
 emulation.  When we try to reset the ADB, it powers down immediately.
 OpenBSD does the same (at least they did with the latest kernel I
 could try from their binary download -- 3.9?).  Linux handles it
 fine.
 
 I started to look through the power management code, but began to
 think that we'd be better off with a rather sizeable overhaul and
 punted for the time being.
 
 There's something else funky with the keyboard.  It appears to be
 a USB keyboard that also appears through ADB emulation of some sort.
 OS X sees three USB busses:
 	1: Bluetooth HCI
 	2: Apple Internal Keyboard / Trackpad:
 		Version: 0.86
 		Bus Power (mA): 500
 		Speed: Up to 12 Mb/sec
 		Manufacturer: Apple Computer
 		Product ID: 0x0214
 		Vendor ID: 0x05ac (Apple Computer, Inc.)
 	3: USB High-Speed Bus
 
 But NetBSD probes several devices here and I get no keyboard input.
 Perhaps because the wskbd0 attaches to the wrong keyboard instance.
