Help with sleep - gfx doesn`t wake.

[Taisto]

Guys can anyone help me with fixing my sleep function ? It seems that both xnu kernels are working in this matter, system sleeps and wakes properly, i know this because i hear it`s working ( adium for example ) but after waking from sleep my gfx shows image for 1-2 seconds and turns off. Im using Mobility Radeon X1600 in my laptop so i have limited possibilities, especially in bios setting. does anyone have any idea what to do to fix it ? I would be grateful.
