Looks like this change was intentional.  Here's what's happening:

led_init calls pdc_chassis_info to find the address of the LCD display.
This then calls register_led_driver, passing it that address that you
have above.  Then the lasi driver calls register_led_driver again, but
it's already been initialised, so it returns silently.  This all seems
correct to me.

If PDC is telling us this address, then it ought to be correct... right?
I don't know anything about the LED/LCD stuff yet, so I hope someone
who does can explain why this is correct.
