holy crap.  just rpm'd the hotplug stuff for fc3. added an appropriate
line to usb.usermap and a script that changes permissions and group
and it just worked. so easy, yet so confusing.  I swear this
hotplug/udev stuff has to be the most confusing stuff i've run into on
linux since maybe the early days of crafting monitor timing lines by
hand for X11 :)  at the end of this message is the bits I added in the
off chance it helps someone.  THANK YOU PETER!

however I have one last issue that I was curious if anyone had fixed. I
am going to see if I can get a newer version of nut hoping it resolves
the issue.  now that its work i'm getting spammed with the following
message is syslog:

usb 1-1: usbfs: process 32652 (newhidups) did not claim interface 0
before use

here's the relevent bits for in /etc/hotplug using mostly fc3 pkgs.

usb.usermap:
ups.belkin               0x0000      0x050d   0x0551    0x0000
0x0000       0x00         0x00            0x00            0x00
0x00
  0x00               0x00000000

usb/ups.belkin:
#!/bin/bash

if [ "${ACTION}" = "add" ] && [ -f "${DEVICE}" ]
then
  chmod 660 $DEVICE
  chgrp nut $DEVICE
