PS3 Black Screen Of Death Fix

I have this DVI-I to DVI-A/DVI-D splitter cable that lets me plugin in my PS3 (with HDMI to DVI-D) and 360 (and Powerbook via switchbox). But I get the PS3 HDMI black screen of death when I turn the 360 _and_ the PS3 on at the same time.

I have to follow a few fixes on the net to make things all good again. 1) hold down the PS3 power button until the second beep and 2) power off my projector (not just standby... complete power off!). I do this with the toslink/spdif cable unplugged. It's annoying. Or is it a M$ tactic to destroy my Playstation fun!?
