OK, now home, tried workarounds, and can confirm that this does indeed
seem to be a duplicate of bug #444139. I did the following:

First I enabled KMS as per comment #3 in bug #444139, which helped
things noticeably, I was able to go to "Normal" visual effects without a
crash, and still had my background, so that was definite progress.
Window animations were still very slow, however.

Then I edited my xorg.conf as follows - the "Monitor" and "Screen"
sections are from Alexandre, for my PLE2407HDS monitor, and the "Device"
section is from bug #444139 comment #47 since I have a Radeon 9200 PRO.
This sped things up noticeably (still not great, but much, much better):

Section "Device"
        Driver "ati"
        Identifier "Radeon 9200"
        Option "BusType" "PCI"
        Option "AccelMethod" "EXA"
        Option "MigrationHeuristic" "greedy"
        Option "AGPSize" "64"
EndSection

Section "Monitor"
        Identifier "PLE2407HDS"
        HorizSync 29-81
        VertRefresh 55-76
        Option "VendorName" "IVM"
        Option "ModelName" "PLE2407HDS"
        Option "DPMS" "true"
        Option "PreferredMode" "1920x1080"
        Option "TargetRefresh" "60"
        Option "Position" "0 0"
        Option "Rotate" "normal"
        Option "Disable" "false"
        Modeline "1920x1080" 148.50 1920 2008 2052 2200 1080 1084 1089 1125 -hsync +vsync
EndSection

Section "Screen"
 Identifier "Default Screen"
 Monitor "PLE2407HDS"
 Device "Configured Video Device"
EndSection
