2.4.18 KT400 support

Hi,

The KT400 agp ids were submitted (and included with a few bits you
missed) around 2.4.20-rc4 time. Like Dave Jones wrote, they are suitable only for agp2 cards ATM (I get a agp3 question in my mailbox every week or so). They are far from useless, lots of people have agp2 cards.

If you want to do everyone a favor, post a patch to document
CONFIG_AGP_VIA is agp2 only on 2.4 right now. (If you don't I might do it one day if only to spare Dave Jones and me a few mails until 2.5 agp3 support is backported)

Regards,

Nicolas Mailhot
