I've just checked in sloppoer PCI checking for 2.0-testing and unstable trees. It should help for those drivers that need to monkey with the base-address config registers (we had previously been disallowing that). Really, applying any check finer-grained than "should this domain be allowed to access this device?" is hard as various drivers need to do all kinds of weird things with the config-register space. Hopefully this may help you get further in getting AGP to work on your system! -- Keir ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
