Bug#606604: xorg: High memory usage when setting "radeon, modeset=0", in /etc/modprobe.d/radeon-kms.conf

["Александр Е. Ивлев" <kocm@inbox.ru>]

Hi again.

I did some more research.
This time I used htop and xrestop for xorg pixmaps monitoring.
First I ran the system and made measurements.
Then I ran a few X applications and made measurements.
And in the end I closed applications, and made measurements.

Here are the results:

kms=1 --------------------------------------------------------

htop:    21184K
xrestop:
Pixmaps: 11641K          Other: 45K          All: 11687K

htop:    29408K
xrestop:
Pixmaps: 32658K          Other: 96K          All: 32755K

htop:    28032K
xrestop:
Pixmaps: 13348K          Other: 47K          All: 13395K

kms=0 --------------------------------------------------------

htop:    43376K
xrestop:
Pixmaps: 12577K          Other: 45K          All: 12623K

htop:    60688K and continues to grow ???
xrestop:
Pixmaps: 35481K          Other: 94K          All: 35575K

htop:    59864K
xrestop:
Pixmaps: 14284K          Other: 47K          All: 14331K
