My IBM RS/6000 B50 locks up with 2.6.11rc1, it dies in atkbd_init():

It fails also on PReP, not only on CHRP. 2.6.10 looks like this:

Calling initcall 0xc03bc430: atkbd_init+0x0/0x2c()
atkbd.c: keyboard reset failed on isa0060/serio1
atkbd.c: keyboard reset failed on isa0060/serio0

So it could not reset it even before, but it was not getting stuch
tough... What about passing atkbd.reset=0?

I will try that.
Adding a printk after the outb() fixes it as well.

Fixes as in "it reports that reset fails" again or it resets the
keyboard cleanly and works fine?

Do you have a version of that i8042 delay patch for 2.6.11-rc2-bk6?
Maybe it will help.

No I don't, and I don't think you need all of it. What happens if you
edit drivers/input/serio/i8042.c manually and stick udelay(7); in
front of calls to i8042_write_data() in i8042_kbd_write() and
i8042_aux_write()?
