What lack of support? Most of the hardware that doens't support Linux is shit anyways. DRI has stable drivers for all the ATi chipsets up to the Radeon 9250. Most other stuff is supported, and new drivers come out every day. All the hardware I've run linux on has been supported very well, even some random off brand NIC. Also, the target audience for Vista Starter isn't likely to be running very new hardware, though that's a moot point because piracy is huge in those countries, especially in China.
