I get about the same on a Pismo/400 .

You mean using the CCE and indirect buffers? That might be possible with the
"UseCCEFor2D" option which will eventually also offer even faster 2D
acceleration when the DRI is active.
Another thing is that there is now infrastructure for motion compensation,
apparently an Intel guy is working on a DRI based driver for that for the
i810/5 chipset. Am I right to assume that the M3 has such capabilities and
when used they would solve all our problems? :)

I guess there is no ioctl/syscall/whatever for that yet?
PS: Sorry about the broken X dependencies - I really shouldn't build packages
with Branden's test packages installed. How can I fix the packages I uploaded,
just upload the same version again or do I have to make a minor bump NMU?
PPS: Jonas, your packages have the same problem. ;)
