It may be worthwhile to try it anyhow before the patch, though I'm not certain
about all the story here.

I run Linux on a P133 laptop, and I really wanted the suspend-to-disk. I
eventually set it up in the BIOS so that after 20 minutes of being suspended,
it saves everything to the disk (to a DOS parition at the start of the drive)
and shuts off. When next I turn on the computer, Linux comes back off the disk
and life is mostly good. The only problem is that I have to reset the PCMCIA
ports and re-start the network, which was easy; the ethernet babbles something
about "eth0: Too much work at interrupt" otherwise.

You may be able to set up a similar thing if your BIOS supports that kind of
option (suspend+time->suspend to disk).  I don't know, though, because this is
an ancient laptop.  It's running kernel 2.4.4 without any special patches,
though I had identical behavior on the 2.2 series.
