I'm not sure where to look for the video ram size. I didn't find anything in the Xorg log file.
lspci -v reports:

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]
 Subsystem: Compaq Computer Corporation Device 00b7
 Flags: bus master, stepping, 66MHz, medium devsel, latency 66, IRQ 11
 Memory at 48000000 (32-bit, prefetchable) [size=128M]
 I/O ports at 3000 [size=256]
 Memory at 40400000 (32-bit, non-prefetchable) [size=64K]
 [virtual] Expansion ROM at 40420000 [disabled] [size=128K]
 Capabilities: <access denied>
 Kernel modules: radeon, radeonfb

My guess: 128M (which wouldn't fit the 32 MB of less theory)

Initial situation:
- Laptop, Compac Evo 610c, Karmic 32 bit
- The well-known garbled output in the gnome-notifier and gnome-system-monitor with compiz off (my normal setting).
- No problems with compiz turned on.
- Problem still present with the current xorg-edgers drivers.

Current work-around:
Automatically generated xorg.conf with a single change:
        Option "RenderAccel" "off"

Test done so far:
- EXA: works but is visibly slower
- KMS: works, but is visibly slower, leaves artifacts on the screen when objects are moved (which will be cleaned up eventually)
