Pcmcia interrupts & power key scancode on pismo powerbook

Pcmcia interrupts & power key scancode on pismo powerbook

[Viljo Viitanen]

First, the power key in a pismo (stock 2.2.18 kernel) produces a kernel
message:
keyboard: unknown scancode e0 5e

this diff fixes it and allows one to bind the power key to shutdown via
init's keyboard request:

Then, after trying to get pcmcia working (pcmcia 3.1.23+stock 2.2.18 says
"*NO* card interrupts"), I finally came across this (long url, should be one
line but outlook probably cuts it):

http://www.google.com/search?q=cache:pcmcia.sourceforge.org/cgi-bin/HyperNew
s/get/pcmcia/ports/10/1.html%3Fnogifs++site:pcmcia.sourceforge.org+pismo+pow
erbook+success+pcmcia&hl=en

But even with that patch, I get a kernel panic if I remove the card 'on
fly', without cardctl eject (I'm fiddling with a lucent wavelan silver
card).

I can live with that even if it's a bit annoying, but what I'm curious about
is why I could not find that patch in no other place than google's cache :)

Try the link here: http://www.mpifr-bonn.mpg.de/div/iri/Archiv/LinuxPPC/PCMCIA.html

It has also references to further pages. (eject etc.)
