No; I had it working with m-a, but I didn't like the zillions of logs it
leaves around so I wrote a small script (that I'm attaching). It's a quick
hack really, but it Works For Me and besides it doesn't require anything
strange except fakeroot and the kernel-headers packages you want to build
against. When I have confirmation that the packages work fine, I'll see if
there are improvements to be made, but I don't think so.

No, I didn't need to do any changes besides the patches I already apply to
my packages.
