MSI K8N Neo4 SLI Platinium: sound, network, USB

Hi, Can someone re-assure me that sound, network and USB can work as supposed to on a MSI K8N Neo4 SLI Platinium modo using SuSE 10.0 in X86_64 smp mode ? On my setup: - only one network jack out of two works. - only stereo speakers are working (plus subwoofer) instead of 5.1 - last time I've checked USB it couldn't see a functional and formatted USB key. At this point I'd just like to know that these can work fully. How to make them fully is another matter and I can take the time needed once I know it's possible. I'm considering changing the mobo. Thanks.
