Can I use 9.04 xorg.conf for missing 9.10 xorg.conf?

Which is all well and good unless there is a problem, such as I have
now. I have 9.04 working fine on one drive, have installed 9.10 on
another drive and the display is not working correctly. The first
problem after installing the nvidia driver 185.xxxx suddenly all the
desktop fonts to the icons and menus shrank to about a 5 point size.
Why isn't the default a human readable standard size? duh!
The other problem I've encountered is in running Torcs and I get a
horrible flicker to the screen when racing which I don't get when I
play torcs on this 9.04 platform. 

My question is can I use the xorg.conf that is currently in
9.04 /etc/x11 and is working without any known problems, can I use that
and put it in 9.10 under /etc/x11 with a reasonable expectation that I
will not break the new 9.10 install by doing so?
