I do use it, and it's very useful. It doesn't fix everything. If I blast
something and end up with a dead program and stuck in ogl mode, then it won't
help me at all. If starcraft (wine, dga) dies on me, my keyboard is locked and
I'm in fullscreen mode. I can recover the keyboard with sysrq, but the video
thing doesn't fix my vc's. I can use X and it's fine, but I LIKE my vc's. The
joystick hack lets me get my consoles back immediately and painlessly :)
(strangly enough, if I wait a while, I get my keyboard back and can fully
recover, but I'm not that patient)

The opinions expressed by me are not necessarily opinions. In all
probability, they are random rambling, and to be ignored. Failure to ignore
may result in severe boredom or confusion. Shake well before opening. Keep
