Well, the grep line checks for your current kernel configuration, and you don't show what output it prints.
The remainer above deals with grub config only, I think it's logical that this can't alter your kernel in any way.
I think the wiki page is pretty clear and correct about this; you don't run a RT kernel, thus using the threadirqs kernel commandline option via grub is the best you can do, and the steps above should have put that in place correctly. If you want CONFIG_PREEMPT, you'll have to compile or install AND run a RT patched kernel.
