Kernel configuration for IBM ThinkPad
________________________________________________________________________________

________________________________________________________________________________

A defconfig is sufficent for the machine to boot. Sound and WIFI must be manu-
ally enabled. A firmware blob for INTEL Centrino Advanced-N 6205 is necessary.
It can be found in the root directory of the proprietary kernel firmware. Think-
Pad specific ACPI options _can_ be enabled.
