This isn't any decent comment on how widespread this is, but my dad has had vista for a while (MS certified company, lots of spare licences... blah blah).
I've used it on one desktop that failed to start up after sleeping with the default action when the power button was pressed. My laptop (Compaq Presario V4214TU) failed to wake up from hibernation (well sometimes... sometimes it would just work fine, seemed to be if it was asleep for a day or more it was more likely to fail), but HP already has a BIOS fix for the problem entitled something like "Fix required to make your computer vista compatible". I've also used it on 3 other PCs with differing hardware and have experienced no problems only one of these came with vista already loaded.
So out of 5 different hardware setups I've only seen 2 problems with sleeping and 1 was easily fixed (the other one probably was too but it never gets turned off so I just set the power button to "do nothing").
