[wellylug] migrate from NVidia Riva TNT2 to ATI Radeon 7500

[Robin Hinde]

If this is a PCI card, it will work fine in XFree86 4.0, provided you add an 
option to the XF86config-4 file to force PCI mode - otherwise the radeon 
driver thinks it is dealing with an AGP card and locks the system up tight 
when you load it.

The relevant section of my /etc/X11/XF86config-4 is:

Section "Device"
	Identifier "device1"
	VendorName "ATI"
	BoardName "ATI Radeon"
	Driver "radeon"
	Screen 0
	BusID "PCI:0:14:0"
	Option "DPMS"
	Option "ForcePCIMode" "yes"
EndSection

It took me weeks to figure this out :-(

HTH...
