kcontrol display module shows wrong driver

This is also the case on my system (HP nw8240 with ATI FireGL V5000 PCIE) and I am using "ati" driver.
I think this is due to quick fix (workaround) done recently by Simon to prevent Display applet to fail completely when proper PCI info is missing for the card.

attach your /etc/xorg.conf file to this bug. I think I know what is going on.

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
