You need to modify the whitelist of the source code of s2ram to allow your
machine to suspend and resume without any special options. Normally the
recompilation and reinstallation of uswsusp is inevitable, but I found 
this trick works without a recompilation:

 echo '/usr/sbin/s2ram -f -a 1' > /usr/local/sbin/s2ram
 chmod 755 /usr/local/sbin/s2ram
 hash -r

As for combining suspend to disk with suspend to RAM, with
uswsusp, you should use s2both. You can also call s2both from the
hibernate script (with all its richness of options), resorting to
the ususpend-both.conf method. Please note that s2both works only
if s2ram works in your system. There is no way to force it to
work if your laptop model is not whitelisted in s2ram, including
the above and similar tweaking, because s2both duplicates s2ram's
functionality instead of calling it. You have to modify the
whitelist source code to allow your machine for s2ram to suspend
and resume without any special options.

See Suspend to RAM 
for instructions about how to whitelist your laptop in the local
copy of s2ram and how to report that your laptop suspend to ram
properly so that it is whitelisted in the next uswsusp release.
