This is because we are using software cursor on XO-1.5. It's to be
expected. It might change in the future.

Background: if we use the hardware cursor, we have to store the
location of the cursor during suspend and restore it during resume. We
can't query the hardware for the location of the hardware cursor. The
X server (which knows about the location of the cursor) doesn't know
about suspend/resume, and the kernel (which knows about
suspend/resume) doesn't know about the X server.
Future solution: DRI2/KMS (move the X graphics driver into the kernel)
