I have the same problem on an IBM ThinkPad laptop, a T41p. Same error message about DSDT in dmesg.

In my case, the system still believes CPU throttling is supported according to /proc/acpi; however, the CPU never actually changes speed.

I tried rebuilding my ACPI firmware as per the comments, but that made things even worse--X then caused the system to shut down.
