Hi Dave,

It might be a PCI Express, I'm not sure. Here's lspci -vvv as root.
Where am I supposed to look ?

Assuming this is a PCI Express card, then what is the proper fix ?
Should I prevent my initscript from loading agpgart (actually intel_agp)
at all ? (I guess udev or hotplug is trying to load it here). Is there
something like agpgart for PCI express ? Or is it useless ?
