No. I don't mean that m68k will take so long to compile. Well, it
does, but it will get there in time for medium or low
uploads. Critical uploads might stress it though. But an extra day
delay isn't too bad.

But what if the kernel FTBFS on mips? It needs to be looked into, the
mips patch needs to be updated, tested, merged and a new source needs
to be uploaded. If the looking into and fixing takes 3 month then that
will be 3 month without a new kernel in etch.

You've got the wrong packages.

The DI kernel udebs (linux-kernel-di-<arch> source) takes the
kernel-image deb, splits it up into kernel and several groups of
modules and builds udebs. There is no Depends there and can't be to
keep the kernel-image debs available.

kernel-image-di-arch ---source---> linux-kernel-di
kernel-tree-X.Y.Z-N <---depends--- kernel-image
   kernel sources

The 'magic' part is the problem.
