keyboard on recent macs

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hello

Neither netbsd-6, nor netbsd-current as of 2015-03-17, seems able to work
on recent macs. The system boots, but without keyboard support. 

In the boot prompt, both a USB and a bluetooth keyboard do work. Booting
with option -c (userconf) let me see a message that may be there on normal 
boot (I cannot tell, it pases too fast):
pckbc: cmd word write error

In userconf, the cursor blinks very fast and keyboard inputs do not show up.

Ayone have a hint on how to handle that one?
