gpio module for elan520 Soekris/Pyramid

[Tim]

Has anybody made the gpio.ko referenced here: http://www.meduna.org/sw_gpio_en.html
f or Pyramid 2.6.19.2? I'm looking to wake up the gpio capability of
my newly acquired net4521. If so, any help would be appreciated before
I set out to make it myself. If nobody responds, I'll report my
results - or issues - with making this module. Thanks!

Tim,

The module is included in the distro. It is located here /lib/modules/
2.6.19.2-pyramid.metrix.net/kernel/drivers/char/scx200_gpio.ko

Thanks John, but I'm getting the following error:

Tim,

You need to use <i>modprobe</i> intead of insmod. To load the module
every time you start the unit you will need to add a reference in <i>/
etc/modules</i>

John,

Thanks, but modprobe acts the exact same way:

pyramid:/# modprobe scx200_gpio
FATAL: Error inserting scx200_gpio (/lib/modules/2.6.19.2-
pyramid.metrix.net/kernel/drivers/char/scx200_gpio.ko): No such device

Anyone? Or is the Elan sc520 gpio in the Soekris 4521 just not
supported with any of the installed modules in Pyramid? In that case,
I'll attempt to roll my own - I just need to know what the story is,
so I can proceed.
