It should be possible to get that working, but I suspect not without
some code changes. I know the current PCIe hotswap driver has ACPI hooks
that would need to be replaced by appropriate hooks into the powerpc
code to perform the right resource manipulation etc...

We do PCIe hotswap on IBM pSeries, but this is using specific FW
interfaces for which we have a dedicated PCI hotplug driver.

Can the slot power be SW controlled on the Canyonlands PCIe slot ?

No. I just checked the schematics. PCIe power supply is directly connected to 
the board power supplies.
