Umm... I just want to make sure we're all on the same page, because Miles'
e-mail sounds like he _might_ be confused.

cPCI != Compaq PCI

cPCI == Compact PCI, which is a hot-swappable bus archetecture (and cabinet
design, and card form factors, and...)

cPCI has no controller.  It's not a controller spec.  It's a bus and
physical spec.  Tho the Compaq PCI controller may give you many of the same
benefits as a real cPCI system.

cPCI is really just PCI, at 33/66MHz and 32/64 bits wide.  It supports
insertion notification, and removal request (open the latches, allow the
software to shutdown and turn off the LED, then remove the board).

Taking the 2 second look at the web page, it looks like they're working on
both infrastructure for PCI Hot Plug, as well as a driver for the Compaq
controller for this thing.  I don't know much about this controler, but I'm
certainly interested in the infrastructure parts.
