[Nut-upsuser] nut suddenly stopped working...

Not sure you've seen it, so I step up:

in the "ps" output, there is: hald-addon-hid-ups
this is an HAL addon, based upon the same code as our old hidups...
this is what I'm working on in NUT to replace.
I've not thought at it before since I've completely disabled hiddev
support in kernel for MGE units, but any other brand that is HID
compliant, should face it.

the detach method might fail since the driver is _used_, not only loaded!

Note that the above is the reason why I've not thrown out _our_ HAL
support: we still need a way to instruct the HAL autoloaded drivers
not to run if we want to use the classic nut . And this will be done
through the new config (nut.conf -> MODE)

I've no clean solution apart from removing / renaming the addon...
