Only 640x480 Resolution Available After Upgrade

[Bob Perry]

I'm running FreeBSD RELEASE 5.4 and recently upgraded my xorg port.  Ran 
into several problems since then, one of which included loss of 
available screen resolution modes.  Prior to the upgrade, I ran at 
1024x768.  Following the upgrade, 640x480 is the only mode available.  I 
had a bad day with the upgrade so I assume I did something wrong/stupid.

Regardless, my xorg.conf file reflects the following:
	Section "Screen"
		Identifier	"Screen0"
		Device		"Card0"
		Monitor		"Monitor0"
		DefaultDepth		24
		Subsection	"Display"
			Viewport	0 0
			Depth		24
			Modes		"1024x768" "800x600" "640x480"
		EndSubSection
	EndSection

I don't believe the file changed and question where else can I look to 
troubleshoot the problem?

Thnx,
Bob Perry
