fails to boot all together; nothing on the serial console.

on the working .32 kernel:

# cat /sys/devices/system/clocksource/clocksource0/current_clocksource
pit
# cat /sys/devices/system/clocksource/clocksource0/available_clocksource
pit

just to be sure, I tried clocksource=pit on the .33-rc1 kernel. It didnt make
any difference.
