Not complete. This will only work if you have an AGP2.0 card.
There is no code here to setup the bridge in AGP3.0 mode, or handling
what happens when it sees a x8 card.  Fully working code is present in
2.5.60-bk if you have time to backport it (hint: I don't right now)

Has no relevance to the patch. pci.ids is only used by pciutils, and
should not affect behaviour of this agp/ide patch.

Also..

Should be capitalised 'VIA'.

Already in 2.4-bk

[PATCH] 2.4.18 KT400 support

[Nicolas Mailhot]

[-- Attachment #1: Type: text/plain, Size: 563 bytes --]

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,

--
