There's _slightly_ more to it than that if you want to actually get a working 
environment.  (For example, I'm feeding ppc an extra patch and a boot rom, 
both from Milton Miller.  The config is useless without those.  I can walk 
you through the status and reasoning of each platform if you'd like...)

I have no objection to people taking the configs I worked out for my purposes 
and using them for any purpose if they want to do so, but my idea 
of "working" involves having a hard drive and a network connection (so I can 
run builds under the emulator using distcc to call out to the cross 
compiler).  It's the minimal functionality _I_ need.  I'm just offering it as 
a starting point, because you specifically mentioned configs for qemu.

If you're looking to compare and contrast configurations, possibly a more 
_useful_ thing would be to convert all the kernel's existing *_defconfig 
files to *_miniconfig files so you could see what they all _are_.

Lemme take a stab at that, actually...
