agpgart -module not loaded automatically

[Gerald Richter <richter@oehtb.at>]

Hello to all!

I finally got my Xpert 2000 card to work propoerly at an even higher
frequency than the wicked Windows-driver :)).
The only thing that bothers me now, is that the agpgart module isn't
loaded automatically, while the r128 is...
If I start the X-server without loading the agpgart-module before, I get
in the XFree86.0.log :

--- (snip)
...
(==) R128(0): Write-combining range (0xe0000000,0x2000000)

I'm not in the position to need the highest possible output of FPS
at the moment, but like it, when everything starts up in optimal
config...

SO: how do I cause the module to be loaded on demand automatically ?
-that means: before the r128.o... -by what is the loading of that
triggered?

thanks for pointers,
Gerald.
