I was toying with the kernel's framebuffer because under xorg 7.3 I get 
the following error:

(EE) open /dev/fb0: No such file or directory

I get this error with or without framebuffer support in the kernel, so I 
wen't ahead and disabled framebuffer.

I only get this error when I allow the xserver to configure itself 
without an xorg.conf file.  I had to stop using my xorg.conf file for 
xorg 7.2 as 7.3 will not set up my external usb mouse using the 7.2 
configuration.   I've updated to the latest xorg-input-mouse and keyboard.

Anyone know what changes I need to make to my 7.2 configuration 
(attached) to get my usb mouse working again in 7.3?

Anyone know if the synaptics driver I used in 7.2 is still useful in 
7.3?  (http://web.telia.com/~u89404340/touchpad/).  Or can I just 
configure the touchpad properties in my xorg.conf?

Thanks,

Chris
