For what it's worth, the SA1100 serial driver has been registered with me on the Low-Density Serial Ports major (204) as /dev/ttySA0-2 (minor 5-7).
Russ is 100% correct that different drivers shouldn't use the same device numbers, unless they are:
a) mutually exclusive, b) interface compatible, *AND* c) handle all arbitration necessary.
If (a), (b) and (c) are all satisfied, it is often justified to share device numbers and device nodes.
