output of lsmod | grep fb:

fbcon                  41760  0
tileblit                2688  1 fbcon
font                    8320  1 fbcon
bitblit                 6016  1 fbcon
vesafb                  8196  0

Is the vesafb the mod you are speaking of?

I have fglrx running--proper output of fglrxinfo--so why would vesafb be 
running simultaneously with fglrx?
