I've not seen any either.

But imagine a simple mask, with a global bit indicating whether the mask
represents on or off bits (basically mask + 1-bit color map).  I'm
imagining embedded hardware here, like what could be used e.g. for a
cell phone or Newton-type PDA.  I don't know that anyone has ever done
such simple controllers before.

The Radeon X driver looks like it uses the alpha blending stuff for the
cursor.  I've not tested it myself, because I don't have a suitable
combination of Radeon + hardware +OS where I can test XFree86/Xorg.

That could change soon though.
