I'm going to be importing my miniconfig patch into busybox in the 1.1.2 
timeframe:

http://lwn.net/Articles/161086/

And it would be easy for uClibc to sync it from there.  There's also an 
existing patch against linux-kernel (which still applies and I'll happily fix 
it up if it stops applying).

The advantage of miniconfig is that it's not version dependent.  You can 
supply the same .config to the daily snapshot and life should generally be 
good.  (It'll die with an error message if it tries to set a config variable 
that doesn't exist, and if a new config entry shows up that you actually 
_need_ to set it won't set it.  But to give you an example, my UML 
mini.config from 2.6.12 still gives me a working 2.6.16-rc4 UML vmlinux.
