I'm seeing this same issue using the NVidia binary drivers (from the
linux-restricted-modules-k8 packages). After about a day, memory usage
on X is out of control (218M VIRT, 159M RES). xrestop shows the
following:
xrestop - Display: localhost:0
Monitoring 36 clients. XErrors: 3

Spark is a java IM client, and "Bug #51000" is the Firefox browser
window I've got open on this bug.
Top shows that both X and Firefox are using more memory than you'd
expect they should be:
4857 root 17 0 219m 159m 12m R 27 7.9 56:55.59 Xorg
6319 graemehu 15 0 322m 101m 25m S 0 5.1 7:53.50 firefox-bin
Note that these usage numbers, both in Firefox and X, steadily climb
with the system sitting idle until there is no free memory left.
