Kernel26-icc compiled with Intel's compiler instead of gcc

Question

I'm working on kernel26-icc, it's the kernel26 but compiled with Intel's compiler. Can't seem to upload it to AUR ("Invalid name: only lowercase letters are allowed.")
http://www.linuxdna.com/
So far I've this:

Then there's of course the config, it's based on kernel26 at the moment,.
I'm building it now, to test. I had to install icc manually because the AUR package for icc didn't work for me. I had to install icc manually (run the installer), but that wasn't enough. Before makepkg, you have to add the icc to $PATH e.g.
PATH=$PATH:/opt/intel/Compiler/11.1/064/bin/intel64
and execute iccvars_intel64.sh which is in that folder.

icc kernel compiles in similar time as gcc kernel, or if there any differences these may be negligible. To be honest I was not really interested in compiling times (was doing somethig else as it takes ~12 min on my system to finish kernel compilation), but rather with overall kernel performance. This is not the same as OS performance, but I am planning to compile firefox with icc and maybe some other stuff (if I am bored enough).
If you have 32-bit OS (I have no idea how it will work on 64-bit), try it. I can't post PKGBUILD for 32-bit icc kernel because I don't use PKGBUILD for kernels or nvidia as I have found it limiting/cumbersome/unnecessary (while PKGBUILDs work great for anything else on Arch).
The only part really annoying is intel server speed. Downloading icc sources (710MB for 32-bit only) tahes two hours. If you try to get 32/64bit sources even longer (1GB download).
32-bit icc PKGBUILD package requires only one modification related to Release Notes otherwise makepkg will fail. Once installed export icc path, edit kernel Makefile and change one line related to compiler: change gcc to icc. You can also add some compiling optimizations.
Pretty easy if you did compile kernel before.
note added:
actually combination of icc and zen seems to have nice effect on desktop responsiveness (this is 2.6.33)
