xorg.conf file for vostro 1000 using compiz in Ubuntu 9.04

I'm sure most people aren't interested in this, but I finally got my laptop (a Dell Vostro 1000) to work nicely with Compiz under Ubuntu 9.04 (Jaunty). I think the key steps were removing every fglrx package on the computer (apt-get remove fglrx*), switching to the "ati" driver in the xorg.conf, and getting the BusID right (I tried copying it from my earlier xorg.conf file, but the value seems to have changed.) However, I added a lot of other things along the way, which sees to have helped the performance, so, for those who are interested, this is the Ubuntu 9.04, jaunty alpha 5 xorg.conf file for the vostro 1000:
