The main compiler for AC 1.0 is gcc 3.4. gcc 4.x is the main compiler 
for "devel" (aka AC 2.0 or what ever it will be) repository. You should 
you gcc from AC1.0 distribution and it was used to build the kernel.

I got new kernel (2.6.12-something) from FC4 compiled by gcc 4.x, but 
like I said - I've never tried to boot it. :)
I tried to build vanila kernel (from kernel.org) with gcc 4.x, but I had 
problems with new version of udev during boot.
So far I didn't have time to figure out what the problem is.
