I suspect it is only needed, when You want to rebuild Your custom 
kernel, but haven't deleted

So is it for me. But if I specify some CFLAGS, for example -O3 
-march=athlon64, the
building fails, but CFLAGS mustn't affect the kernel compiling process 
afaik. There is
COPTFLAGS for that reason. I've also made a PR about this new, unwanted 
but haven't got any answers so yet.

It's nice for me. I had a general protection fault, but I can't prove, 
that ULE made that,
I had similar with 4BSD. FreeBSD 6 is quite stable for me when I don't 
use my nve network
interface that has a poor driver.
