Problem with Sax

I am running OpenSuse 11.0 on an Acer Aspire 5010 which is a 64bit AMD based system with an ATI graphics card (X700). I use the fglrx driver and am happy with it.
The same cannot be said of Sax. I have just tried to amend the keyboard from microsoftpro to acer_laptop using Sax via Yast. It changed the keyboard but also changed the monitor definition to totally the wrong size and resolution. It also modified the fonts to a whole set I do not have and made a number of other detail changes. The original xorg.conf was OK and worked well and Sax appeared to read it in.

Is there a known problem with Sax (I notice at least one similar thread)?

Has OpenSuse/Yast/Sax kept up to date or could it be a problem with my system?
