Nearly everything else works great. LAN support is a bit funny. The ethernetcard sits on the usb bus and only activates itself as soon as a cable got plugged in. Then a usb asix device pops up and works great (with the asix module).
Sound needed “options snd_hda_intel model=5stack-digout” in /etc/modprobe.d/sound to work under 11.1.
WLAN is a Ralink RT2860 which works with the module rt2860sta. For 11.1 there are kmps in the buildservice, but they never worked for me. I compiled the sources from the ralink homepage and noticed that the driver works well until udev renames the device from (originally) ra0 to wlan0. Afterwards it does not respond anymore.
The fix that worked best for me was to compile the rt2860sta version from kernel 2.6.30 (in staging tree) for openSUSE 11.1. To make it easier to use this i put it here (yes, i’m too lazy to build a kmp .

P.S.: Actually to make wlan work with the packages from above repository from alex you have to blacklist rt2800pci.

P.P.S.: I also recommend to update this machine to the latest BIOS version available from MSI (currently Version 1.0D). As only with this i get fully low-power C-States correctly. To install it i used the package UpdateFirmwareKit and a normal USB-Stick.
P.P.P.S: No, you better don’t update your BIOS to Version 1.0D. It seems this version totally breaks suspend on this machine. I couldn’t find a s2ram parameter combination still working (before just -f worked). Not even with current 2.6.30 it works. I contacted MSI about this and hope they provide a solution for this problem. … Meanwhile as a first response they sent me BIOS Version 1.0C, but that also has the suspend problem. Hopefully they either fixup their BIOS or provide me the working 0.9 Version.
