hmm.  now i thought the suspend capabilities were provided by
pm-utils, which is supposed to let g-p-m know about what's available.
pm-utils sees the tuxonice stuff, so maybe the issue is that pm-utils
doesn't send the info up to gpm.  just to confirm, we're talking about
hybrid suspend, right?  in which the kernel suspends to disk but
powers down to S3, so in effect you suspend to RAM with a backup to
disk.
