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)
