Subject: Avoid early hang when i8042 controller is missing
Patch-Mainline: no
References: bnc#528811

On latest machines without i8042 controller LED control
will hang when BIOS option "PORT 60/64 emulation" is enabled
(which is required for specific extra storage BIOS to work).

Workaround for now: Don't touch LEDs at all.
