The following is what I sent to you a week ago. I don't say whether
CNS3xxx support should stay or not, of course.

I'm still using CNS3xxx-based Gateworks' boards (Laguna), with some
custom patch set, but the last kernels are over 2 years old. I have some
plan to update, but the probability it will happen very soon is rather
low. I guess I will test and, if needed, fix it when the time comes.

I'm not using them with OpenWrt, though.
They are basically a platform for (the old, parallel, not express)
mini-PCI cards and similar stuff. Nothing connected to the Internet etc.
