The location differs between the 2.6.34 and 2.6.37 kernel (since things
are being generalized).

You'll find the base configuration for the atom-pc in 2.6.34 in your
'linux-yocto-stable-2.6.34+git0+e1f85a470934a0cf6abde5d95533e74501822c6b_0+72ca49ab08b8eb475cec82a10049503602325791-r1/linux'
(that's a mouthful) directory.  On the wrs_meta branch.

Then you'll find: wrs/cfg/kernel-cache/bsp/atom-pc/boot-live.cfg

If you send a diff against that, we can merge and make the change
permanent (assuming it is suitable for general use).

Cheers,

Bruce
