I was having exactly the same problems, AMD64 ATI 9200, random crashes in firefox etc.
Solution was to install fglrx drivers and change xorg.conf to point to fglrx instead of ati
driver:"ati"

one note - the fglrx driver wont output via DVI, so you will have to plug your monitor into the analogue output of your video card to get a display http://www.ubuntuforums.org/showthread.php?t=21927&highlight=fglrx+blank+screen
