This seems to be resolved on Lenovo Thinkpad T410i with a bios update. I notice the original posted dmesg has the version 1.25 listed, The latest is 1.43. Going from 1.32 to 1.43 seems to have resolved this issue on Lenovo T410i running 12.04 64bit. Same bios update applies to T410 model also. Bootable iso available from lenovo support pages.
