Hmm, are you really sure that you did compile the kernel with icc?
What was the exact commandline you compiled the kernel?
I'm just asking, because recently I noticed, that doing a
CC=my-gcc make
for the kernel tree does not work as expected, because the 
Variable definitions in the Makefile have precedence over the 
environment Variables. If you want to override Makefile variables
you should use
make CC=my-gcc
or explicitly instruct make to give environment variables precedence
with the -e option.

I can't remember exactly where I've read this, but there might be some
problems with passing variables by environment to configure.
In the autoconf manual is just a short note:

"Variables not defined in a site shell script can be set in the
environment passed to `configure'.  However, some packages may run
configure again during the build, and the customized values of these
variables may be lost.  In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'.  For example:

     ./configure CC=/usr/local2/bin/gcc

will cause the specified gcc to be used as the C compiler (unless it is
overridden in the site shell script)."
