2.4.26 agpgart on Tyan K8W 32bit not working?

[gb]

Howdy,

I'm using the generic 2.4.26 kernel on a Tyan K8W
(dual opteron) with 4GB of memory and an NV18GL
[Quadro4 NVS] graphics card.  The K8W BIOS version is
2.02 (1.02 also exhibits the same behavior).

On a 64bit kernel, the following is returned:
