Justin,
I've tried removing your check, for writing bonnie++ still reports slower write times then IDE drive on the other system. Daniel Phillips was great at helping me notice a problem that was causing slow down but not related to the aic7xxx driver, thus I am now trying the 7.4.8-ac8 kernel.
I made your change whe will get try to get my user to test the system with and without your change.
