For values of big changes that equal the attached patch.

I'm using it on 2.6.10-mm3.  I sent it to Zander however since there is
no way to detect the new multi-agp support barring some sick hacks it
has not gone in.

It may conflict with the support for the 2.6.11-rc kernels, in which
case when I next upgrade I'll find out and write a new one.
