Thanks for testing that, it rules out a common cause of these problems. Sorry to have you keep testing stuff over and over. :-) I think this bug should have gone upstream long ago. I'd like to do so now, but the first thing is that they will wish you to re-test against a newer version of the -ati driver.
I've uploaded the latest 6.11.0 driver to Jaunty the other day. When Alpha-5 comes out in a couple days, I would like to ask that you download and re-test it one more time. If you can reproduce the problem then we should forward it upstream.
I dug into the changelog and see that there has been a fix to your chipset since the 6.9.0 release:

Fix VT switching on M6 chips
Some M6 chips have a faulty MEM_SIZE register that in
some cases reports 0 on 8 MB cards. On EnterVT we check
the MEM_SIZE reg as a check to see if the card is posted or
not. Since this reg returns 0, the driver attempts to post
the card which can lead to a hang. Switch this to check if
either crtc is active as is done in the bios init code.

However, the symptoms of this bug differ from what is reported here so I'm not entirely sure this fix would solve this freeze issue. But I think it would be helpful if you could re-test jaunty before we upstream the bug.
In addition, can you run the command `lspci -vvnn > lspci-vvnn.txt` and attach that output here?
