with some versions of tar replace I with j, or use
bzip2 -cd /path_to_downloaded_kernel/linux-...tar.bz2 | tar xvf -

That tip is just meant as an FYI for newbies.

Is it safe to not touch them?  I never realized that a person vould
want to change /usr/include/linux.  Is this going to hurt me if I have
never changed them, since a 2.2 kernel?  And is there an easy way to
check what version is in /usr/include/linux? (I don't have a linux
system infront of me), can you just open one of the files and see the
version in the header?  Is there a way to query glibc to find out what
version of the kernel it was compiled against?

Thanks,
