Well, we do have NVRAM do not we?

No. I unplugged power, removed battery and left it over night. Today morning it has shown exactly the same behavior upon resuming (well, upon power-on after suspend to disk :))
To recap - this never happens upon simple power off; I do not remember this to happen upon suspend to disk until 2.6.19 (I won't claim it never happened, just that I do not remember it). This happens consistently in 2.6.19-rc5. I am very curious which hardware issue may have such pattern. And in any case this does smell like regression (earlier version not triggering this HW issue if any)
