What bug exactly?

I'm sometimes using kernels compiled with gcc 4.0 and without
-fno-unit-at-a-time and except for the kernel image being smaller I
haven't noticed any difference. Besides this, all architectures except
i386 and um are not disabling unit-at-a-time.

There are a few parts of the kernel that might still have stack problems
with unit-at-a-time, but I assume that's not what you are talking about?
