That rather depends on where the disk came from.
Since it is relatively easy to move volumes between machines [1]
you actually need to look at the disk to find the label info,
neither a header file nor the kernel know where it will be.
(Clearly the kernel knows what it found if it managed to mount a fs.)
The i386/amd64 code plays 'hunt the disklabel' :-)

[1] Otherwise we wouldn't need support for byteswapped fs.
