Hmm - I tried disabling HW cursor and it still happens - which makes me whether it's actually hardware specific; but I've not seen it on anything else.
The xorg.conf I put in to stop it was:
Section "Device"
Identifier "Configured Video Device"
Driver "mga"
Option "SWCursor" "True"
Option "HWCursor" "off"
EndSection

and /var/log/Xorg.0.log now includes:
[ 19.707] (**) MGA(0): Option "SWcursor" "True"
[ 19.707] (**) MGA(0): Option "HWcursor" "off"
[ 19.707] (==) MGA(0): Using AGP 1x mode
[ 19.708] (**) MGA(0): Using SW cursor
Odd.
