While most netbooks use common intel chips, some use the GMA500, which is yet badly supported for linux. An open source driver "may" be there in Q4 2009. But as the video decoding acceleration benchmarks show, it might be worth waiting for it. It's not only good, but also energy-efficient at decoding even HD material. The bad thing is though - there's at the moment no yet any well working Linux driver available. And you can't even know for sure it will ever come. If you're still interested, check out the MSI Wind U110.
