Hm - I used the nv driver but got the same behavior only when using dual head.
For me it turned out to be that firefox seems to hold onto bitmaps way too
much. Especially when you browse webpages with lots of images, that quickly
gets to be a pain. xrestop showed that most of the memory used by X came from
firefox - Pxm mem column... There are some xorg bug reports out there for
that behavior, but most of them revolve around xinerama too.

and many others - they are old and still in new status... On the mozilla pages
you will see similar reports...
One solution that seems to work for many is switching to the nvidia closed
source drivers. If you want to stay open source, try nouveau.

Both of them can fix the high pixmap memory usage for some people. Others have
no luck with either.
