The above was with apic enabled. With apic disabled, same story tho different
boot-time message:

$ cat /sys/../state
suitable: 1
enabled: 1
apic suitable: 1
using APIC: 0

dmesg gives:
Unable to query Synaptics hardware.
input: PS/2 Synaptics TouchPad on isa0060/serio1

and X refuses to start. Same resolution, just reload psmouse.
