There's a lot more to X than the video memory and pixmaps.

In my case (this is X.org 6.9.0 on 6-stable/amd64 but the principle is
the same), I have 32MB video RAM, 28MB pixmaps and ps report that X
is using 78MB - a difference of 18M.

If I look at the process memory map (see procfs(5)), the breakdown is:
38MB  vnode backed (mostly shared libraries)
32MB  device (video memory)
 6.75MB swap + default (malloc'd space, stack etc)

This suggests that X is storing a lot of pixmaps in video RAM (for
efficiency).
