Yes,  same results

The .ko snd_maestro3 file can't e loaded without it pulling in snd_pcm.ko (and 
snd_pcm.ko can't be unloaded while the maestro3 .ko is loaded "Device is 
busy" is the message)

The first load always disables the keyboard clicking (from BIOS) the ^G bell 
in the CLI and sound in X (using KDE and artsd, I haven't tried just plain 
twm).  The unload/reload process still wakes everything up.

My idea well is dry.
