agpgart fails with Via KT400 and GeForce 4200-8x

Hi all,

I have a system with Via KT400 Mobo and a GeForce 4200-8x
graphics card.
When I try to load the agpgart module, I get the following
message, that agpgart is unable to determine aperture size:

---- output of dmesg -----------------------------------------

Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 203M
agpgart: Detected Via Apollo Pro KT400 chipset
agpgart: unable to determine aperture size.


This happens with 2.4.19 , 2.4.20, 2.4.21-pre2 and -pre4.
I think this a problem with AGP-8x.
Is there any chance to force AGP-4x or to tell the module
about the aperture size ?
