Please consider adding the following sensor support to fc5/6 (upstream support is a work in progress afaik): http://lists.lm-sensors.org/pipermail/lm-sensors/2006-August/017484.html (note that there is a follow-up patch in the thread to clean some bits up) In particular, this is to support the Supermicro X7DAE and similar type boards.
Fedora policy is not to merge not-upstream drivers where possible. (The only exceptions being where Fedora/Red Hat kernel engineers are actually working on the driver). We'll pick this up when it gets merged into Linus' tree.
