Ubuntu Intrepid hangs Thinkpad X61.

I've reinstalled Ubuntu Intrepid this morning, and I've since upgraded it to the latest updates, including thinkfinger and trackpoint scrolling.

No hangs yet (crossing my fingers).

The only difference from my old installation, though, is I haven't reinstalled conky on this one. I think I'm 99% sure it was conky indirectly causing the hanging because of the repeated ACPI calls. Come to think of it, I think the thinkpad never hung prior to installing conky on it.

Here's my .conkyrc, for reference (just in case I lose the file in some careless reinstall):
