Readme for linux-2.6.22.1-config:

This kernel config gives me zero test failures from Glibc (and the rest of the
toolchain).

I overkilled some stuff, which I rarely use and can't remember what hardware I
have, such as the I2C and Sensor stuff.

It can be used as a template. If you want to expect no Glibc failures, then
don't remove any drivers and just add the drivers for your hardware. After you
achieve a perfect Glibc test suite, then begin removing drivers and retest to
narrow it down to minimal for your system. It's probably safe to drop my disc
controllers, and the I2C/Sensor stuff, on your first attempt.
