While I don't strongly state anything, why? AFAICS in changelogs, gcc 4.4.x has all significant features we want to use (like SSP), 4.6.x has probably not too much important for us improved C++1X support, more strict compile time checks, better standards conformance, and many changes in Ada, Go, Fortran, etc.; support of new -mXXX, non-x86 archs support/improvements, etc. I'll try to make 2.6.18 kernel compilable with gcc 4.6.1.
