Drivers are stored in linked lists in the kernel.  They are added to the list 
when the driver is added via the SYSINIT() in DRIVER_MODULE().  The order of 
SYSINIT's with the same (subsystem, level) depends on the order the modules 
are loaded (and even the order that files are linked when the kernel is 
built.. since the Makefile has the files in alpha order, this means /dev/aaa 
will usually get probed before /dev/bbb if both are in the kernel for 
example), and since psm(4) and acpi_ibm(4) both returned the same probe 
priority for this device, the first driver to probe it "won".
