[opensuse] 64bit Kernel and 32bit Userland - how to do it?

I've just ordered a new workstation, with a Core 2 Quad CPU. I want to run OpenSUSE with a 64-bit kernel and 32-bit userland on it. I have not had a 64-bit CPU desktop with OpenSUSE yet, so I'm asking for advice -- what's the best way to do it? (My Google foo was not good enough to get good answers. :-( )

AFAIU, 64-bit OpenSUSE comes with 32-bit userland programs. Do I get all programs this way, or only a selection?

Or, do I install 32-bit OpenSUSE and replace the kernel with a 64-bit one from the build service / factory / vanilla kernel? (I have no problems compiling my own kernel -- I started using Linux with 0.99.4, back in 1995...)

In case you're wondering why I want that constellation: I prefer 32bit userland for its stability and availability of media stuff (e.g., win32 codecs), but I also want to run 64bit OSes in VMware instances. For that I need a 64bit kernel. In addition, it will handle my 8 GB main memory better than a PAE kernel.

Oh yes, the release of choice will be eventually 11.1; in case that matters.

Thanks in advance for any recommendation,
