Hi Mihails,

please take a look at the code in drivers/parisc/led.c.
There you'll find a few "workarounds" for Kittyhawk machines and
some explanation, why it maybe doesn't work.

 ** we explicitly check for those machines here.

Maybe you try to change some coding there, else I'll try and continue=20
to figure out next week....
