You should be able to do this:

sysctl dev.acpi_ibm.0.eventmask=134217727

then have devd match the incoming "IBM" events and spit them out to console.
Once you know which affect what, you can then create a script to match 
all of them causing hotkey like actions customized for your machine...

see /etc/devd/asus.conf for an example, but obviously our codes are 
different and unfortunately I don't have an example nor recent memory.
You probably want to get devd to be very verbose and determine what the 
codes emitted are.
