Added Support for new Intel ICH6 chipsets (confirmed to work in ICH4 mode).
Corrected device ID of AMD8111 chipset, should work now. Added more device IDs taken from Linux driver (untested, but should be similar to ICH6) Note: ALI chipset ID is not enabled yet, as it needs a different interrupt handling. Cleaned device probing up a lot. This is now much simpler, and has less verbose debug output. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12930 a95241bf-73f2-0310-859d-f6bbb57e9c96
