I see you're running at 24 bit. Are you sure you were using 24 bit in sarge?
That's probably pushing your luck on an M6 at that resolution.
It might help if you post the X log and xorg.conf from your sarge setup so
we can see where the differences are. I'd suggest trying it at 16 bit first

It says in your X log that DRI is not working because you're too short on
video memory. It says you only have 16Mb of video ram. Again, a 16 bit mode
will probably use much less video memory and therefore DRI will probably
just start working if you switch to 16 bit.
