This problem has been reported by various people since at least pre5. I
still get this message upon boot with the latest pre kernel:
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 204M
agpgart: Detected AMD Irongate chipset
agpgart: AGP aperture is 128M @ 0xd8000000
[drm] The mga drm module requires the agpgart module to function correctly
Please load the agpgart module before you load the mga module
The problem is that neither of these things are modules, they are both
compiled in. I can't exactly change the loading order, and in any case
it appears that agpgart is initialized before mga. Here's my /proc/pci in
case it helps:
