There have been patches around for a while. Despite having a laptop that
does not feature suspend-to-disk at all, I have not used them. There are
semi-regular reports of yet-another disk corrupting bug in the swsusp
patches...
The mailing list is probably a good place to visit, at least before
committing. Links from:

Watch out for recent releases. Everything from 2.5.1 to 2.5.5-pre*
corrupted data on-disk for me. 2.5.6 is stable, without extremes of
load[1], running IDE disks in DMA mode.
PIO mode disk devices are still broken, in data-corrupting ways,
apparently, in that revision. I have not tried anything newer because
they have vastly /more/ dramatic changes to the IDE driver in them.
So... do take a backup before you go playing with the 2.5 series. :)
