I have the same problem on my Toshiba Satellite L650-BT2N23. So far I have tried Ubuntu 9.04, 9.10, 10.04 and 10.10, in addition to other distros such as OpenSuSE, Fedora and Mandriva. I have also tried rebuilding some of the older Kernels with the 'copy_dsdt' patch described here (https://bugzilla.kernel.org/show_bug.cgi?id=14679), but nothing has worked.
