I've udpated the BIOS on my T61 to 1.26 to match yours, but running 2.6.24-rc5 I don't see the issue you reported.
If it still fails for you, please send me your .config
thanks,

It has been fixed in -rc4 I guess.

Yakui,
Can you look at this. Seems to be coming from commit f79f06ab9f86 FixedHW support tries to read MSR with interrupts disabled.
Thanks,

Subject: ACPI : Delete the IRQ operation in throttling controll via PTC
Quoted 1 line
From : Zhao Yakui <[email protected]>
The IRQ operation(enable/disable) should be avoided when throttling is controlled via PTC method. It is replaced by the migration of task.
