Then we would need to support that attribute forever. IMHO the best
option is to just make a uname call and check the kernel version, with
the code marked to be removed in the future when kernels older then
$version are no longer something we want to support.

Oh, this doesn't work *at all* with distro kernels backporting everything 
that passess by to kernels with major versions looking years old.

I (as one of the "guilty ones" with my distro hat on) am not at all saying 
it's perfect, but that's the way it is.
