This reason would still be in the logfile which stores the state of the
system, such as lsmod. It's just a summarization about what went wrong
that in case pm-utils knows the exact reason why it failed.

But if it would be done in pm-utils, pm-utils would also useable without
HAL, so it would be some kind of separate. HAL would only be the interface
between the desktop and pm-utils.
Can't we agree on a preamble and postamble pm-utils writes to the log?
