I couldn't tell from your posting, but are you aware of the generic UNIX
C program supplied (at a small fee) by BEST just for this purpose?  It is
supposed to run on the HP, and monitors the serial port every couple   
minutes.  When power is interrupted, the program detects this, and lets
you do whatever you want to shut down the UNIX system.  We plan to start
a modified "shutdown" script, ending with reboot -h, after stopping all
other processes.
We haven't installed all this and made it work, but we have the hardware 
and software, and an approach that ought to work.  You can also help reach
your scenario by changing the settings in the UPS that control how long the
UPS will run after AC-line interrupt, whether it will restore power when AC
returns, etc.
Sounds like we have similar setups and needs (BEST UPS, HP9000, Novell).
Stay in touch; we can probably both benefit.
NOTES:  the BEST software comes as source on DOS 5 1/4" disks, with a manual
        for installation and customization.  It is cheap (<$100) compared to
the UPS, anyway.
Hope this helps,
