Emil, that is exactly what I asked, and he explained. He is using ZaphodHeads,
so the two driver instances in X log are both for the same one card, only
different outputs. The other card is not taken into use, and I don't see error
messages related to ignoring it, either.

He should be having three driver instances in X logs, as per his configuration.
He is missing all the instances for the card "04", IIRC.

He is also using Xinerama.

Thomas, maybe it would help to show the X and kernel logs, when you try to use
only the problematic card (GPU)?

Makes me wonder, if cold booting doesn't really support dual-GPU card's 2nd
GPU...
