You can buy it officially with Windows 7 now, it seems to be fully supported. http://www.samsung.com/us/consumer/office/mobile-computing/netbooks/NP-N130-KA04US/index.idx?pagetype=prd_detail&tab=support > > While were at it I have another question: When running on battery the > > ethernet throughput drops to ~25Mbit/s.

I haven't actually tested throughput in Windows, but ISTR that there was a Samsung app where you could configure various power saving features. Might have been the "SAMSUNG Battery Manager".
