[Problem]
After a resume from suspend, the color depth changes from 24 bit to 8 bit.

[Original Description]
After resuming my Acer laptop (with Ati Radeon x700) from suspend, the color
depth of X changes to 8 bit or similar. Originally it is set to 24 bit color
depth which is presented after the boot process but it degrades after the first
suspend/resume.

I have two machines theoretically with the same configuration (except the hard
drives are different). Both are the same acer ferrari 4005 WLMi model. In one
of them the color depth degradation still appears while the other one suffers
from Bug #524860 related to gnome-keyring but color depth changes after
suspend/resume does not appear.

I did the following experiment: I switched on both machines when booted up I
logged in, suspended and resumed. After these I coppied the file from
/var/log/Xorg.0.log to

Xorg.0.log_homepc (refers to homepc suffering from color depth changes after
resume) and
Xorg.0.log_hardnut (refers to the other laptop without any issue after resume)

Please, find the difference between the two files here below. (It seems that
the two radeon x700 cards are a bit different)
