to be complete enough, still in testing mode:
- start both the driver and upsd with "-u root"
- send back a more complete driver output (Ie, the answer to "I" is missing
above)
- send back outputs from upsc / upsrw / upscmd
- test the shutdown using (requires upsmon to be started too, as root):
http://www.networkupstools.org/docs/user-manual.chunked/ar01s06.html#UPS_shutdown

I'm holding the commit of a new hardware compat list entry until you send
these back.

cheers,
