The kernel does not compile with gcc 4.0:

Uh, right.. Horms, would you prefer to keep 2.6.8 in unstable for working
on security stuff, or can we remove it?

I'd like to keep it there. I'll take a look into how bad
the gcc-4.0 issues are here. If its too painful, I guess
we should pull 2.6.8 from unstable.

Ou seja, o problema é o gcc4, até agora está indo bacan com o kernel 2.6.12
