 What we need to do is port code from Linux which stores information on

+-------------------------
+Network and blkdev drivers are bloating Xen. At some point we want to
+build drivers as modules, stick them in a cheesy ramfs, then relocate
+them one by one at boot time. If a driver duccessfully probes hardware
+we keep it, otherwise we blow it away. Alternative is to have a
+central PCI ID to driver name repository. We then use that to decide
+which drivers to load.

+Most of the hard stuff (relocating and the like) is done for us by
+Linux's module system.
