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. Matt
