Thanks a lot. I'm trying to get a complete collection of working drivers to avoid the searching from the various sources of all kinds of Thinkpad
and OSx86 forums. Unfortunately I can't help too much, I don't get along with the Chameleon 2 Bootloader.
My files will be listed here:

I added a list of all vendor and device ID's of the x61t. It would be great if anyone could create a complete LegacyX61.kext as a base. My tablet is an X61t with Core2Duo 1.6 GHz, 8 GB RAM, SXGA+ display and standard BIOS. The 2nd Mini-PCIe-Card is an Broadcom CrystalHD Video Decoder. The Macmodel entry in smbios.plist should be MacBookPro3,1 (Core2Duo/Merom) for the x61 and MacBookPro1,2 (CoreDuo) for the x60.
Pedrone: I know this kext with the incorrect brightness, looked strange

Do you have graphics mode selection? I have a 1400x1050 display, that's the main reason why I'm searching for a really 100% driver. OpenGL also was always in slow motion, have you tried the OpenGL test in Xbench? I never got fully working graphics, neither in Snow Leopard or Lion.
