I've tailed it during buildworld and the only informations written there are from my atheros card. Another question: Ian Smith asked here on the list why the fan levels in acpi_ibm would not have not been implemented yet to 6.x. Since my notebook started overheating when moving to 7, could that be a reason? On my first mail to freebsd-stable I also quoted a case from the LKML where someone with a X60s reported overheating and the problem was in the fan levels of the (linux) acpi_ibm module, if I recall it correct.
