suggested patch

[Paul Goyette <paul%whooppee.com@localhost>]

While building a custom kernel with drm (radeondrm, in particular) 
configured, but with vga only at pci (ie, no agp), I discovered drm's 
"option DRM_NO_AGP" is required to avoid a number of linker errors.

Enabling this option in the kernel config resolved all but one of the 
link errors.  The following patch resolves the final error.  This is 
certainly not within my area of expertise, so I've not committed this 
without some level of discussion/confirmation that this is the right 
thing to do.

Comments appreciated...
