actually, there's a really easy way to do it -- install the tuxonice
kernels and tuxonice-userui from nigel cunningham's ppa:

this is part of the enhanced functionality of tuxonice, which has been
blocked from the mainline vanilla kernel for years, largely because of
recalcitrant kernel devs.  a shame, really.  it's conceivable some
elements of this might be merged into the kernel in the near future, but
it doesn't seem that likely right now.  see the recent threads on
linux-pm, linux-kernel, and tuxonice-dev lists.


ps, there are a couple of extra steps involved, if you can't find them
on the web somewhere write back, and i'll post a link.
