Thanks, this is a significant step forward in building a good 
omap1_defconfig.  Cory, do you mind testing this out?  If it works for you 
also, let's plan to take this for 2.6.38.

However:

This is also key.  Until the board files can somehow indicate which rate 
sets are usable for their boards at runtime -- which is what the 
CONFIG_OMAP_ARM* KConfig options used to do at KConfig-time -- I don't 
think omap1_defconfig is possible yet.

Volunteers to tackle that project are gladly welcome :-)
