I think it would be good to fix this in the gcov tool. When I think of distribution kernels the source usually ends up in a different place in the packages than the kernel was originally compiled. So it would be good to extend gcov here or let it search in well known locations first (/usr/src/linux, /usr/src/debug/...).
Cheers, Jan
