After the dust has settled and I've used the GM release for a couple of days I thought that I would write up what does and doesn't work for my part.
Stuff that doesn't work
VMWare workstation; It will not compile the needed modules after install. A patch was made for 11.4 RC1 if I remember correctly, but it doesn't seem to be updated to support the GM release yet.
Stuff that just works
Amazingly enough, the prop. ATI drivers works without a hitch for my part (Radeon HD 5850). It's the first time ever that it just works out of the box by downloading and executing the installer from the AMD/ATI website.
KDE 4.6 is a breeze to use, everything is working out of the box, and it looks smashing! You won't regret running KDE this time. At least I don't.
Well, since everything is working as it should with 11.4 there's not much more to say. Just a very big thanks from my part to Novell and the openSUSE developers and the community!
