BIOS: 1.32 / ECP: 1.12
(New) Added support for new CPU models.
(New) Added support for NVIDIA Optimus models.
So looks like this is why they switched back to NVIDIA.
I'm happy with my T410 (integrated) but i know some people were clammoring for Optimus or even Switchable on the normal T410 as this seems to add that.
