The same board as mine and the processor; and if you were born 1974 then lots of things in common here ;-)

Sleep was working fine for me on vanilla installation, just some fake plists, both automatic and manual sleep. Only 'problem' i had was to wake up from sleep; had to press power button to wake up. Solved that recently by tweaking dsdt some more with usb tweaks. Now it can wake (from deep sleep) with keyboard press or mouse button press (won't wake up just on mouse move) but its still an achievement. Both keyboard and mouse are USB.

I had no black screen issue even before the last usb dsdt tweaks with my 8600GT. What are you using for HD3650, is it an EFI string, some injector? With proper efi string we could replace gfx section in my dsdt and i can send it to you so you can try that option too.
