Mu investigations where that the BIOS controlled Fn+F2, but it could be the kernel module which I did not suspect at the time and so have not tested. On my EeePC 1000, bios previous to revision 1003 did not controlled Fn+F2; acpi-eeepc-generic needed to be used to enable/disable wifi. On newer bios though, the bios seems to control directly the Fn+F2. See my entry about it on acpi-eeepc-generic's wiki: http://code.google.com/p/acpi-eeepc-generic/wiki/Wireless
