"Common" yes, but they should not be normal.  The whole point of the 
config(1) mess is to be able to properly specify dependencies.

As I indicated in a follow-up Email, I still need to include a

	vga* at pci? dev ? func ?

to avoid a compiler error.  But I have already removed the

	wsdisplay* at vga? console ?

line.  The only wsdisplay line I currently have is

	wsdisplay* at radeondrmkmsfb0

which, according to the dmesg, is where it actually gets attached!
