A lot of BIOSes allow you to tweak it and pick the suspend type
(sometimes you need to hit e.g. ctrl+f10 or whatever the magic command
is to enable the hidden features).

Failing that, perhaps something as simple as "sudo chmod a-w
/sys/power/state" would work (there are likely other nicer ways to do
it, just thinking with my "hacker" hat on).
