Does not work with OSX 10.6.3 nor OSX 10.6.4 nor 10.6.5 with all flavor
QE_CI patchs 10.x.x

when the machine boots I see all the BIOS POST messages, then the

Chameleon screen followed by the white screen with grey Apple logo, and then

just when it should display the login screen the nonitor says "no signal" and goes black. I have tried all 3 outputs and it is the same for all of them.

Any workaround?
