I think the question was: what's the difference between the Qtopia *images* and the ASU images.
IIRC, the ASU images use X, even the Qtopia apps on the ASU image use X, but the Qtopia images do not have X, so the apps on the Qtopia image write directly to a framebuffer. So the ASU is OpenMoko's port of Trolltech's Qtopia, to run on X.
Apps on the pure-Qtopia image have to be specially written in order to run on the Qtopia image, to deal with the frame buffer. I'd also guess that'd mean that the apps are faster, since X performs like an arthritic snail.
I'm not sure where the Qtopia image comes from either. Does it come from Trolltech? The ASU image comes from OpenMoko.
Because the ASU uses X, then all kinds of other apps using other toolkits (Gnome, ETK, etc.) can co-exist beside the Qtopia apps on the ASU image.
Example: I'm using the openmoko-terminal2 (which appears to be GTK), on ASU, alongside the excellent Qtopia apps.
