I just booted 2.6.24.2 on pq2fads (using cuImage, since I don't have a 
devtree-aware u-boot on this board).

This is wrong; the flash will not translate since you didn't provide a

The first cell of the reg should be the chipselect, and the second cell 
the offset.

BRG should be <119f0 10 115f0 10>.
