Do we have a memory footprint evaluation of ubuntu-desktop?

All,

It was found that the ubuntu-desktop is a bit memory hungry on this i.MX53 QuickStart board. There is a large chunk of memory being reserved for the graphics/video drivers, and the memory size reserved has to consider the worst case. And we have to live with this before the unified memory allocator is available.

I don't yet have a /proc/meminfo after system is right up, I'll get some statistics a bit later. However, I do want to know if we have some memory footprint evaluation of the existing ubuntu-desktop (we are using unity-2d)? And what can we do to improve on that?
