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:

Bugzilla entry for 2.5 is here:

Please apply. Thanks.

In fact I've been cleaning up a bit the 2.4 version before
submitting it -- the entries for other VIA chips are a bit
more convoluted and I suspect the first patch is not as
complete as it should be. In fact I think I'll post a 2.5
followup soon.
Please do not apply the first patch and use this one instead.
I didn't tested it myself (not enough time) but Johannes
Winkelmann reports it as ok. It's pretty straightforward
anyway, just id lists all over the place.
Best regards,

Which was webmail-borked. Sorry, should not have let the other
submission rush me.
Anyway here is a cleaned-up tested version for 2.4.20-rc4. It's
basically a straight port of the 2.5 patch, plus the dri bits I missed
in 2.5 (purely cosmetic, but hey not having his dmesg full of unknown
chips is always nice), plus some kt400-related pci ids for the database.
The effect is the same as the patch that went in 2.5, with a few nicer
printks.
Please apply
