I went down this path with my Epia M10000 and got mixed results.  I am 
using Fedora 3 and found a site that keeps recent kernels and packages 
for software suspend in Fedora 3 and 4.  The link is 
http://mhensler.de/swsusp/ if you want to check it out.  Getting things 
set up was no real problem, as I recall it basically consisted of 
installing the hibernate package, installing a custom mkinitrd for 
swsusp and installing a patched kernel.  After that, software suspend 
worked like a champ simply by executing the hibernate command as root. 

Overall it works well, boot times are roughly 30 seconds to resume from 
suspend mode.  This could probably be faster but my Epia a little anemic 
in the processing area.  The main reason I have not been using hibernate 
is that the resumed Unichrome driver has some sort of problem with 
Myth.  Although I can see the desktop/frontend perfectly whenever I 
attempt to play a recording myth just displays a black screen with audio 
(I'm not using XVMC so I don't think it's a problem there).  At this 
point I got frustrated and never really looked into what the exact 
problem was.  If you fair better with your Epia let me know any tips/tricks.
