Comment(by ohshima):

 I'm certainly willing to help to debug, but not familiar enough with the
 driver code itself.  Setting the cursor form is done by
 display_ioSetCursorWithMask() in:

 http://squeakvm.org/cgi-bin/viewcvs.cgi/branches/olpc/platforms/unix/vm-
 display-X11/sqUnixX11.c?rev=1901&view=auto

 So you could take out -O2 flags from a few Makefiles in the VM build
 directory, run a gdb session in X or in console, set a breakpoint at
 perhaps ioSetCursorARGB() in sqUnixMain.c or
 display_ioSetCursorWithMask(), set arg /usr/share/etoys/etoys.image and
 run and step the function.

 This may not be what you are looking for (if so, sorry), but this would be
 my suggestion.

 If the schedule is real tight and we don't have enough time to fix it, one
 thing we could do is to stop using the cursor with alpha for the release.
