The driver tries to detect all controllers it supports. Since the
ncr53c8xx supports both the 810a and the 896, all your controllers should
have been detected. When loaded as a module, the driver must be loaded
once (btw, a seconf load should fail).

What hardware are you using (CPU, Core Logic and tutti quanti) ?
Is the 896 on PCI BUS #0 or on some sort of secondary PCI BUS ?
Does the sym53c8xx driver show same behaviour ?
