Regarding hardware - 

1. AMD Athlon 1700+, VIA KT333 chipset based MB, nVidia GeForce 2
2. AMD X2 Athlon, AMD690V chipset based MB, nVidia 7600GT
3. (current) AMD X4 Phenom II,  AMD780G chipset and nVidia 9600GT 
(binary driver for video card every time)

Recently I tried kernels 2.6.26, 2.6.27 and now 2.6.29. Kernel 2.6.26 hibernated, but booted
up without recognizing image, so no attempt to resume was made.

Kernels 2.6.27 and 2.6.29 are able to resume, but thats about it - after resuming the box 
doesn't respond to keyboard and I have to reset it.

s2ram doesn't work as well. So far my best result is one succesful suspend/resume cycle; 
second attempt to do the same ended in black screen and the computer became "confused" -
reset (and I mean hardware reset with button on the case) didn't work - I had to turn it off
completely.

I have been using hibernation for quite some time (starting with kernel 2.6.14 or so) 
and never managed to get swsusp working. On the other hand tuxonice (and swsusp2
before the renaming) is - except for some glitches - working all that time.

I admit this is completely user's point of view, but I wanted to point out, that for some of us 
tuxonice is currenty way to go.

JB
