are you running lenny?
what version of ati driver are you using?
if you're using the fglrx driver (which looks like it from your xorg)
have you had any luck by using aticonfig?
after you install the driver you run
$ aticonfig --initial -f
that will give you a clean xorg.
for me the newer xorg versions have picked up everything automatically.
so ditch the big xorg.conf if you can.
i run on a hd3870 and it's perfect using the ati 8.9 driver.
all i had to do to get 3d acceleration was install the driver and run
aticonfig. to get compiz i just added the
compiz "enable"
line at the end of my xorg.
i've attached my current file for you to look at if you need it.
