user-space. The thought of writing the code to walk the PCI device tree looking for an AGP controller is not a pleasant one, but I may be over complicating things in my mind.
Linux at least exposes some of the PCI info publically (see libpci, /sbin/lspci) and allows read of some basic config data space by all.
Remember when walking the PCI tree that it can change. X hasn't really joined the 1990's on the issue of hotplug but please dont make it worse 8)
Ugh. That is an issue. I don't think it's likely that a card plugged into an AGP slot will get moved to a PCI slot, though. :) Do you have any recommendations on how to do this "right?"
