[Soekris] GPIO for net5501 under Linux 2.6?

I want to control the error LED on the net5501 under Linux 2.6.  With a bit of 
hacking* I got a GPIO module designed for the 4801** to compile and install.  
With it the temperature sensors work but I'm unable to control the LED.  From 
the CS5536 data book it appears one needs to clear bit 4 of MSR 51400015 to 
use be able to use GPIO20.  I tried doing this but it had no effect.  Has 
anyone gotten GPIO to work on this hardware under Linux?  Thanks in advance.

* See the attached patch
