Actually, if the -rt patches follow the normal patch name convention,
they should be applied to 2.6.16 not any of the stable team releases
[2.6.16.x].

You might be lucky though if the patches that the stable team applied
are compatible to the -rt patches [which they probably are most of the
time].

If you use the wrong patchlevel [-p0, -p1, etc] the program patch might
get confused because the patchfile doesn't seem to fit. The canonical
way to apply the -rt patch to a kernel ist:

tar xjf linux-2.6.16.tar.bz2
cd linux 2.6.16
patch --dry-run -p1 < /path/to/patch-2.6.16-rt20
#if previous line ran without errors do:
patch -p1 < /path/to/patch-2.6.16-rt20

Have fun,
