Sorry about not replying earlier, didn't have time to examine the
patch until now.

That's not a problem for the "megatec" driver. My own UPS doesn't
identify itself either.

The patch looks like it is only modifying fentonups to accept that
model, without making any other changes (to correct calculations,
etc). Am I wrong?

Then megatec (and powermust on the stable branch, for that matter)
should aready drive that UPS. If it doesn't - check if battery.charge
ever reaches 100% -, care to send me the output from "upsc"? (It can
be the output just using powermust, it doesn't need to be megatec).
