Debian :: When Suspend And Hibernate Screen Goes Black?

I am having some pain with my new Squeeze installation, I am not sure if I am asking to much of it or it is an easy fix.

Firstly my system is laptop which I regularly plug a second monitor into. The video adaptor is an ATI HD4550 mobile.

My problem is that when ever suspend or hibernate my system, and even sometime when I boot up the screen(s) are just blank, although sometime they don't, it always happens if I suspend by closing the lid of my laptop, and only sometime happend with through Gnome is go ->System->Shutdown->Suspend. This is really annoying.

Another issue which I think is connected is that as I said I have a second monitor (most of the time) and when I boot up then it works until I log in, then a message pops up say the configuration can not be applied and it revert to Mirror mode or it does this thing where it places the second screen inside (virtually) the built in Laptop panel, it will not let me fix this through the monitors dialog just displaying the same message. I can fix this by doing

invoke-rc.d gmd3 restart

This gets as far as killing Gnome them it prints an error the to console, at which point Imopen a new terminal by ctrl+alt+f2 and
invoke-rc.d gmd3 stop
invoke-rc.d gmd3 start

then it works fine and even remember that I set the secondary screen to be the primary monitor through xrandr.

I tried install fgrlx drivers instead but it didn't really fix the issue, so I removed them.
