Yes, that's right. Replacing the do_suspend_to_disk action misses out some
of the built-in functionality:
- ignoring button events after resume
- reset CPUFreq settings after resume
- it confuses our internal event management, which runs asynchronous and
thus needs to know how long the system slept
It may work all the time, but still can cause problems.
So the easiest and most clean way to integrate uswsusp is to hack
/usr/lib/powersave/do_acpi_sleep. I think that should be pretty easy. I
hope we (seife or myself ;-) can do this the next days so that I can put a
version update to sourceforge.

Holger
