I also found an interesting tidbit that I didn't know - I read that all stable versions have an even "minor" number and all development versions have an odd "minor" number. Found it here - ( http://www.leicester.lug.org.uk/meeting/m000713/Kernel_versions/kernel_versions.html )

the 2.4.22 is the base kernel from kernel.org that everything is built
on top of. the 1.2153 is a CVS ident (so gets bumped with every change
I check in). the .nptl is 'native posix threading library'.
glibc does various magick if it finds its running on a 2.6 kernel,
or a 2.4 kernel with a .nptl suffix. If it doesn't, then it falls back
to the older threading model iirc.
