Thanks for fixmtrr.sh !!.. it solved the slow performance problems in my
Intel 945GM running Ubuntu/Kubuntu 9.04.

BTW, I am using the older xserver-xorg-video-intel-2.4. 
If I use the default xserver-xorg-video-intel 2.6.3, then fixmtrr.sh fixes the performance issues, but causes screen corruption, which can be clearly noticed when switching windows using Alt+Tab !!
