Are you already aware of the events mentioned in acpi_ibm(4)?
Quote:
| devd(8) Events
| Hotkey events received by devd(8) provide the following information:
|
| system "ACPI"
| subsystem "IBM"
| type The source of the event in the ACPI namespace. The
| value depends on the model.
| notify Event code (see below).
|
| Depending on the ThinkPad model, event codes may vary. On a ThinkPad
| T41p these are as follows:
|
| 0x01 Fn + F1
|[...]
| 0x15 Volume Up
| 0x16 Volume Down
Either way, I think you're looking for:
/usr/src/sys/dev/acpi_support/acpi_ibm.c
