I'm not so sure that they can. The various issues do actually seem to
need OpenMoko staff to solve them. Look at all the work Andy is putting
into solve GPS issues, kernel issues, etc. And Joerg on the GSM
issues. I don't think that OM have enough staff to do all of the that
and write Glamo code.

I'd agree with that, if that happens - but that hasn't happened yet.
You're imagining the worst possible outcome here? Perhaps I'm too
naive. Although I can imagine a scenario where the OM team would move
quickly onto the GTA03 once the GTA02 is 'good enough', the community
can keep the pressure up to 'do' something with the glamo chip when the
other issues on the GTA02 have been solved.
Is the glamo graphics stuff the 'most important' thing that should be
done? i.e. in firmware on the glamo chip? The qtopia image (which uses
a framebuffer?) seems to get reasonably good performance without
anything extra. Maybe just a bit more work needs to be done in the
Xserver to stop it doing 'expensive' ops (as Raster suggested?) rather
than full on acceleration in the chip. This is something that could be
done in the community. Complex stuff, either way.
