Don't apply either! There is a known issue with that busybox, and the magic:sys doesn't install. The known issue with busybox leads to a reboot cycle (search for nokia white screen of death on these forums, if memory serves).

The reason those are showing up is because you're using the SDK repository on the device. There are big warnings on the maemo repository page that say not to use them, BUT! there are lots of programs that work well from that repository, so I use them too.
