Yes, it should be possible if your sources are in synchronization with
world/kernel.
Just make the edit and go to /usr/src/sys/modules/acpi/acpi_ibm and type
make && make install
You'll notice that fan speed becomes something ugly after trying to set
brightness, but everything will work otherwise as far as I have tested.
I have found that the machine gets quite hot on its own especially with
turbo core on the i7 and heavy usage, even with power tuning.
Adjusting fan speed could be dangerous, I would certainly keep a close
eye on temperatures during something like buildworld to be sure.
I think the brightness ec address could be wrong in acpi_ibm, leading to
corrupting the fan speed value, but that is conjecture.
