+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).
