I'm very interested in this as well. I have always wondered why the scrolling is choppy and vsync doesn't seem to be honored; while investigating I noticed that Xorg is indeed using fbdev!
I'm going to take a shot at getting a real video driver up and running.
I notice the Meego 1.1 build for the n900 includes:
xorg-x11-drv-fbdev-sgx
I'll try to get it running under Maemo.

Maemo's "fbdev" is actually == fbdev + sgx extensions, which is better than -omap3.
We call it fbdev-sgx in MeeGo as to not conflict with existing -fbdev for other systems

Well, do you know by chance what's causing what appears to be tearing (or at least jerky motion) when, for example, switching desktops?
I assumed the fbdev driver was lacking some 2d acceleration capabilities and it was just a standard bitblt or something.

Has anyone ever tried the omap3 fb driver? Googling shows no results.
edit: I tried the omapfb driver and it gave me the same corrupted result.
