Hi!
Having ukbd in the kernel, and not uhid, makes uhid load as a module 
during boot and attach to the keyboard, even with your patch.  I'm 
recompiling the kernel now with uhid as part of the kernel to see if it 
makes a difference.  I'm not too confortable hacking /etc/devd/usb.conf, 
but if you can point me in the right direction I'll have a go at it.
Regards!
