Only if all users and distro's install pm-utils ;) They can also get
it now by 'apt-get install hibernate'.

uswsusp will certainly not start stopping services, it does however
do some things you also seem to be doing, like switching VTs (pm-utils
does that rather hackishly, IMHO) and fixing the state of the graphics
hardware. 
But it can also do things pm-utils will never be able to
do, like encryption and compression of the image and showing a splash
screen during suspend and resume.

Well, you should make better advertisement then, it is hard to find
pm-utils. AFAICF there's only your cvs repo.

If nobody beets me to it, I'll be making a debian package some where the
coming weeks.
