Yes, but the vast majority of it is C.
ben@magnesium:~$ locate "/usr/src/*.[Ss]" | wc -l

ben@magnesium:~$ locate "/usr/src/*.c" | wc -l

Don't take this as meaning the ratio of C to assembler is 30:1, since
the .c files may well be much bigger, the .s files are usually just
one routine which has been optimized (e.g. some libc functions in
/usr/src/lib/libc/i386). There is almost certainly more C and less
assembler than 30:1.
