The Via VT8237A controller (e.g. Asrock 775Dual-VSTA, Asus M2V) is not supported in gentoo-sources-2.6.17-r7 (unfortunately the 2006.1 livecds too). It's only recently made it into the kernel.org trees: http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a7dec1e0dbb9e8e032b56a62d07ab6ac009109d3 http://www.kernel.org/git/?p=linux/kernel/git/smurf/linux-trees.git;a=commit;h=08be09b7c38a71b1677285c10a08725833ff9b95 Attached are some patches I made (and am writing this using!) against gentoo-sources.
