Yep, sounds like we are in the same state. I've not been around long
enough to know the whole history for sure, but it appears that Nigel has
worked for quite some time on swsusp on 2.4 and Pavel has worked on a
2.6(pre) as different branches some original "swsusp". Now that Nigel is
going 2.6 the two branches are rather different and hence Nigel's 2.6
version is called swsusp2 while his 2.4 version is just swsusp. Somewhat
confusing... So far Nigels stuff is only available as a patch.

Well, I can say that my system suspends and resumes flawlessly from
2.4.x with accelerated X - I've had several hundreds of cycles since I
installed (early autumn). No crashes at all, but a handful of failed
suspends while hunting down some incompatible drivers - for instance the
LinuxAnt driver for the builtin wireless card...
