Because gcc-4.4 is the default compiler, but the kernel has been
compiled with gcc-4.3 (mainly to avoid regressions that may show up when
building the kernel with the newer compiler).

That the kernel folks are rather insane and insist on building
third-party modules with the same GCC version as the kernel is another
problem (consider what would happen if libraries were handled that way).

They should look at the CC environment variable first. I don't quite
know if/how Debian's linux-kbuild infrastructure takes care of setting
that, but there is a file
/usr/src/linux-headers-2.6.32-5-$flavour/.kernelvariables in the
linux-headers-2.6.32-5-$flavour package that seems to set CC.
