Really need some help with KDE & X11 Upgrade

[Jamie Griffin]

I am using KDE 4.10. I would like to use KDE 4.12. My OS version is FreeBSD 
10-Stable. 

Can I use KDE 4.12 with the xorg server version 1.7.7_11,1?

If I need to use xorg server 1.12, will I need to build it using WITH_NEW_XORG 
and WITH_GALLIUM in /etc/make.conf; or, should/could I build xorg server 1.12 
without these options? (Video card information from pciconf included at the 
end of this message.)

I wondered if I should upgrade the xorg server first and try it with my 
current version of KDE (4.10) first of all, to see if my hardware functions 
with the newer xserver. 

Finally, is it now possible to carry out these upgrades using pkg? I read 
about the 'WITH_NEW_XORG' repository at 
http://pkg.freebsd.org/freebsd:10:x86:64/new_xorg/. Or is it recommended to 
use poudriere, for example, to build it all locally and then upgrade?

I really would appreciate some guidance with these questions if possible. I've 
already made one attempt to upgrade this software but I couldn't start the 
xserver and/or KDE because it crased X11. It took days to restore everything 
back to the older versions which do work nicely.

Many thanks for your time, Jamie.
