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. Jan -- The default Magic Word, "Abracadabra", actually is a corruption of the Hebrew phrase "ha-Bracha dab'ra" which means "pronounce the blessing".
