Hi, I was the person who cleaned up the code a couple years back. I don't own a Fujitsu notebook anymore, but here's some information from what I remember.

My S6010 had hardware volume control (it was separate from what was ALSA controlled). I'm not sure if this is still the case with the Fujitsu's S and P-series notebooks. > > +static int acpi_fuj02b1_get_pointer_state(void *data) > > Less sure about this one, but I'm not sure exactly what it's meant to > do - control whether the mouse pointer is enabled? I never used this, but I think it gives the user the ability to disable the built-in touchpad. Probably driver dependent. > > + acpi_bus_generate_event(device, event, (u32) fuj02b1->volume_level | > (fuj02b1->mute_state * 0x1000000) | 0x10000000); > > ALSA is capable of generating events when the mixer volume changes, so I > don't think there's a need to explicitly generate an event here > (assuming you move the mixer over to ALSA) Since the buttons control the hardware volume control, I believe the events were more for displaying OSD volume status.
