Thanks dragorn.. I'll check out lorcon.

I suspect it might be some endian-ness issue with my packet formatting on MIPS.

When you write packets via a raw socket they show up to other monitoring interfaces; while kismet should handle it fine, either your header is corrupt, or so minimal that kismet is throwing it out because it doesn't make sense.
