NOTE 1: This worked for me with my card (lspci says "ATI Technologies Inc Radeon R250 [Mobility FireGL 9000] (rev 01)"). Your mileage may wary. Also, as I'm writing this after I got this to work there might be some errors in the description below. If you find one please let me know.
NOTE 2: DRI doesn't seem to work for me right now. I haven't looked into it any further. Let me know if you get it to work.

To downgrade x.org I had to add the Edgy repositories to /etc/apt/sources.list. Just copy the lines for feisty and replace feisty with edgy. Here's what my sources.list looks like:

sudo dpkg -i envy_0.9.1-0ubuntu4_all.deb
