What's this? 2.6.26-rc6:

input: PC Speaker as /class/input/input5 PCSP: Timer resolution is not sufficient (4000250nS) PCSP: Make sure you have HPET and ACPI enabled. PC-Speaker initialization failed. pcspkr: probe of pcspkr failed with error -5 === A HPET I do not have, ACPI is enabled and the driver worked fine on a previous -rc.

That means that the high-res timer mode is not available. See cat /proc/timer_list It should contain the lines like .resolution: 1 nsecs 1 nsecs means a high-res mode. Some large values (like 4000250) means low-res. Try adding the hrtimers people to CC if this is a problem.
