Hello Dave,
after suspend-to-ram and a subsequent resume the configuration
of my AGP bridge/controller is different and X will refuse to
start after resume if it wasn't running during suspend. I'm
using radeonfb as console driver and kernel 2.6.13-rc6-git6.
Diff between lspci -vvvxxx before and after suspend follows.
