Convention tends to be that these bus types are exported.  That's certainly 
true for pci and mca.

However, perhaps we should have a better way of finding them than by direct 
export of the symbol.  Since each bus is required to have a unique name, and 
the sysfs system has an internal list of bus_types, we could have a function 
which takes the name and returns a pointer to the bus_type if it exists?
