Are you using this daily? Just want to know if there are any gotchas I might need to check before I start using it.

I used the kernel module for a few days and didn't notice any problems on a laptop running Fedora.

The kernel module is less that 100 lines long, hopefully it's simple enough to not cause trouble...

May I ask, how is it possible to prevent unloading the module?

The module takes an extra reference count to itself upon initialization and never decrements it, so rmmod will fail because the module will be "in use".

Nice ;)
