[PATCH] [2.4] AGP Support for VIA KT400

[Leif Delgass]

Hello,

Here is a small patch to support agp for the VIA KT400 northbridge.  It's
against 2.4.20-rc3 and is based on Nicolas Mailhot's patch for 2.5 which
was included in 2.5.49.  It adds the PCI id and registers the VIA generic
setup routine for the chipset.  I've tested it successfully on a Gigabyte
GA-7VAXP (KT400) with a Radeon 7500 using DRI and various GL apps/games.  
If this has already been submitted, just ignore it -- but I hadn't seen a
patch for 2.4 appear on lkml or the BitKeeper site yet.

Nicolas' patch for 2.5 on lkml:
http://marc.theaimsgroup.com/?l=linux-kernel&m=103786946803970&w=2

Bugzilla entry for 2.5 is here:
http://bugme.osdl.org/show_bug.cgi?id=14

Please apply.  Thanks.
P.S. Please cc: me on any replies, I'm not subscribed to the list.
