Another point on your bug graph. I have a T430i running 3.7.9-1 Arch linux 
x86_64. With the 1.20 bios I have working brightness keys. I was unable to get 
my own bitmap boot splash screen image into 2.05 so I gave up on 2.x updates. 
Anyone else have any experience with the 2.x bioses eg improved tp acpi etc etc 
(sorry for hijack)?
