You can certainly send me patches for defconfig updates.  I go through
and update them all (via make xxx_defconfig; make oldconfig) after -rc2
is available, but I might not set everything exactly as you would want
to see it.

If there's a chicken/egg problem in that there are drivers or changes
that went upstream but aren't in the powerpc branches yet for one reason
or another, you can poke me about getting things pulled in.

Since I'll be doing defconfig updates today, just tell me which options
you need set or disabled.
