well my dns on my raq3 still ain't working but i was wondering which patches should be applied from http://asiapac.cobalt.com/support/download/raq3.eng.html ?

There are two theories on this:

One, is that the patches fix problems. Good.
Two, is that tha patches cause *other* problems. Bad.

What I suggest is to watch the mailing list (the archives) and see what is said about the updates before you install them. The list is quite aware of the problems that can be created when 'patching', and you'll generally see a message by a brave soul who says they installed the patch and the machine *didn't* start smoking and melt.

Just don't apply the patch the *second* it comes out.
