Uhh... I use suspend to ram with Windows 2000, works just fine. I've seen
it work just fine with Windows XP as well. When it doesn't work, it is hard
to be certain where to place the blame, since suspend to ram requires both
hardware and software compatibility. However, in my experience all new
versions of Windows support suspend to ram just fine, but sometimes specific
hardware and specific applications sometimes have some trouble with it.

Windows 2000 and surely other versions of Windows also support suspend to
disk. Windows 2000 calls it "hibernate." You can access the settings for
it (and suspend to ram, and other power saving features) from the icon
labeled "Power Options" from the control panel. If I recall correctly even
in the days of Windows 95 (or at least 98) the laptop version of those OSes
normally also supported suspend to disk. Suspend to disk really isn't as
good as suspend to ram though for a desktop computer. It is much slower,
especially if you have say 1GB of RAM. Even with a decent hard drive
capable of reading at 30MB/sec., that would take over half a minute to load
the contents back into RAM (or shut down for that matter). On the plus side
though you don't lose all the data in your unclosed applications if the
power goes out like with suspend to ram.
