Two thoughts on dealing with DRAC:
drac appears to have both a pckbd0 and ukbd0. either will take
console. remove pckbd from your kernel config, and in ukbd.c hardwire
that unit 1 gets console, and plug in a keyboard.
boot with serial console instead (on 0x3f8, which on a 610 is the real
serial port)
