Several months ago, I tested a pre-release against building the kernel. 
At first, it did not work. Then it did. There was a bug, though, that I 
reported and that was corrected and several syntax modifications.

But, more important, I wasn't able to really see a difference between a 
kernel built by GCC 3.3 and by GCC 4.0. There is some fuss about the new 
optimizing feature, but I remain a bit sceptical, until someone 
definitely proves it really goes faster (on a i386 machine). I did not 
do extensive testing though, so my advice is not worth a penny.
