10.5.7 black screen after sleep

[bullys1974]

Hi there...
i am running on 10.5.7 updated from IPC10.5.6.
darwin kernel 9.7.0

my specs are:
gigabyte EP35-DS3 F3 bios
Intel quad 6600
6 GB RAM
ATI HD Radeon 3650

my system goes to sleep via Apple-Sleep
Fans turn off - monitor turns off
Everything fine

When i hit the power button to turn the system on, it starts fine, but the monitor remains black... no DVI-Signal.
I have to shut down my system via keyboard - ctrl - eject - enter
That is a problem i never solved since 10.5.2

i tried everything around the solutions here:
- superhai USBEHCI
- different BIOS Settings
- sudo pmset autorestart 1
- some patched kexts
- voodoo kernel 9.6.0

none of them worked for me...

where is the problem ?
there seem to be a solution i didn´t test, because i dont have the option "restart after power failure" in my energy savings in the system settings...

how can i gat this option to be displayed ? which are the kexts that displays that option ?

Pls help to wake my system after sleep.

cheers bullys
