That's the correct way :-)

But the OP asked if there was some magic way to get genkernel to use the same 
config as #SOME_OTHER_KERNEL.

Which of course makes no sense as there can be multiple versions and configs 
present.

The small remaining part of me that is still mostly unaffected by the onset of 
senility seems to remember genkernel being able to do something expressed as:

zcat /proc/config.gz > /usr/src/linux/.config
genkernel [....]

Which I suppose is a reasonable thing for an app like genkernel to do.
But I could also just be imagining it. It happens :-)
