Before redoing a whole bunch of work that already exist, please, please, please check the howto. Harrald Roelle has already done an extensive PPC patch, available at :
In fact, Harrald sent me a second version of the patch (not on his page) that was *very* promising.
The patch of Harrald is not in the main Pcmcia distribution because Andy has been busy lately and Harrald doesn't feel confident enough to send them to David.
Please contact Harrald to know how you can help.
