[Nolug] Major kernel version, or "extracting substring from a symbol"

Hi,

We all know that "uname -r" gives the exact kernel version. How
do I extract out the "2.4"?

The reason I ask is that there are certain steps in my PC's boot
process that I only want to run if I'm booting into 2.4 (and I'm
sure there will also be some if I'm booting into 2.6).

Thanks
