Hi Randolph,

Nice patch !

I've tested it on my 715/64 (with LEDs) and on the c3k (w/ LCD).
On the 715/64 your patch works as expected, but on my c3k I neither
get anything on the LCD nor the /proc/pdc/lcd file.
I know that this doesn't happen due to your patch because I 
didn't got the LCD to work before applying your patch too.
As far as I debugged it until now the pdc_chassis_info() call in
led_init() now returns -10 (PDC_INVALID_ARG) as result code, so maybe
something other is busted here.
Maybe you have any idea ?
All tests were done with the same 32bit kernel binary on both machines
and with your patch to inventory.c applied. I never tested a 64bit kernel
in case this should be relevant.
