The latest version of the aic7880 chip on the latest Asus P2L97 boards
require a setting that the previous chips didn't.  That was fixed for
5.1.3 or 5.1.4 aic7xxx driver.  The official 2.0.36 kernel already has
that fix and before long I will have some unsupported/unofficial kernel
RPMS for redhat 5.2 that will fix it as well.

      they should be everybody's.
