Certainly, I'm not opposed to that, patches welcome. Synchronous
failures, however, are not very common

There's a small technical obstacle insofar that method calls on the
non-standard interfaces on HAL implemented by running a binary can only
returns integers (not true for addons, they can return anything they
want). This is probably something that is fixable though. I'll look into

The stuff in HAL will still write a preamble (with e.g. /sbin/lsmod
output) and possibly a postamble too. I think that belongs in HAL, not
pm-utils, because HAL provides the asynchronous error handling, pm-utils
