Greetings,
Since I've been debugging the pcmcia driver, I thought of something andriy said 1-2 years ago when pcmcia was buggy.
In order for 2.6.17 to have working pcmcia we needed to add this patch below.
Andriy said he knew this wasn't the best way to solve it, but we should use it until he talked to you.
Currently this isn't applied to neither jlime-current.git or any other git tree. Could you please give me some quick feedback on why this might be nessecary (or was). I always assumed It would be obselete ones MMIO transition was over.
