 Sorry, I neglected to mention I'm using a custom kernel, which seems to
 be the contributing factor. I've used the same config for years without
 issue; it predates the introduction of gpio devices, and so was missing
 those lines. Apparently after the last changes pulled up, gpio devices
 are now required for a complete boot. I added:
 
 bcmgpio0	at obio?	# pins  0 ... 31
 bcmgpio1	at obio?	# pins 32 ... 53
 
 gpio*		at gpiobus?
 
 It now boots properly. (The firmware wasn't an issue: I was able to
 boot a kernel built June 3rd with the firmware update from July 26th.)
 
 I should have mentioned the custom kernel aspect last night, I was a
 bit sleep deprived. (Apparently I also couldn't spell "Raspberry"
 properly...) Sorry to waste your time.
 
 Thanks,
 
 Dave
