It looks like the problem was your display driver. In order to support
suspend, the driver for your display may need to be updated. And
display adapters from some vendors will probably never be made to
support CPR, because the vendor has to provide sufficient programming
information to fully initialize the device without reliance on BIOS.
Many (most!) video hardware vendors do not provide this information.
(There are some workarounds available in certain other circumstances --
I think, for example, that Nvidia has developed their own
Nvidia-specific solution. In any case, at least some Nvidia displays
suspend properly.)
