	Oddly enough, for me, the sound comes and goes, so I haven't been able to pinpoint the source. Crappy power input could be the reason, but I'm not sure. Sometimes I get a whine even when it's unplugged. So, in summary, I get whines from a number of places for a number of reasons, but I'm not sure why. USB and lots of hd access seem to be the main reasons. So far the best solution I've found is to just run cpufrequtils with ondemand or powersave governors to get it to not speed up unless I have to.

		+	I guess I've got the same high-ptiched whine on my R61i as well. I've been trying to pinpoint the device, and I never realized it was the AC adapter (it's not the adapter itself whining, but something on the base of the laptop). I've been playing around with my kernel, wondering if there was a module that accessing some hardware would initiate the whine or not. So far, the main culprit I've found is loading the UHCI module (USB 1.1 driver) really made it scream when I first got it. Then it seems like it happens whenever the harddrive is really busy (Gentoo + compiling == a lot of access).
