[drm]: why does drm.ko/radeon.ko load agp.ko for ATI HD4670 on a PCIe system?

My lab's box is running FBSD 8.0-CURRENT/amd64 and hardware is based on 
an ASUS P5K Premium mobo, P35 chipset with ICH9R and PCIe. The graphics 
card is a MSI HD4670.
Apart from the fact this box does not well with FreeBSD 8 and HD4670 is 
unusable with driver 'radeon' in port's X11 (xorg-7.4), I always get 
module agp.ko also loaded when loading radeon.ko. Why? This box does not 
have AGP! I do not see this weird behaviour with a FreeBSD 8 box running 
the same source code, nearly the same configuration, but UP and with a 
HD4830 board (which does quite well). X11 is of the same date/source stage.
