Rafael J. Wysocki (a suspend maintainer) has written an article speaking about the current status of suspend and hibernation support in Linux, its design, know problems, and future development. "Below is a document describing the current state of development of the suspend and hibernation infrastructure: how it works, what known problems there are in it and what the future development plans are (at least as far as I am concerned)."

I guess I'm also blessed on Linux (well Ubuntu specifically), as power management works perfectly on mine (well at least suspend, I never hibernate so I have no clue if it works, just suspend on lid close, and I'm closer to 100%). On Windows XP, after suspend, the screen backlight will not go on without weird FN key combinations that are somewhat random if it will go back on or not. It actually had the same problem with Linux until g-p-m implemented a workaround for the "hardware bug" about a year back. Now its flawless in Linux, but Windows XP still doesn't work. My laptop won't run Vista at all...
I thought the problems were getting more rare now as long as there is a nvidia card inside, I know I had big problems with this laptop when I was on Gentoo and the early Ubuntu's, but it was fixed before 6.06 (I think for 5.10 if I remember right) and has worked great since.
Not sure how my desktop does with suspend on Linux, never tried really, never had an interest. I think mythtv will wake from suspend to record, so maybe if it is reliable, I can use it to save power (and reduce heat output which would actually be the nice part)

I have an HP dv9000, and it works great about 95% of the time, even with compositing turned on.
But I may just have a blessed laptop or something, because I don't get any of those vista bugs everyone complains about either.
