Well, it doesn't really matter *in context* of getting this patch
accepted for mainline. It needs to be properly described on its own so
people can review it without looking through dozens of forum posts.

Sorry for not following that closely, I lagged behind due to my work on
other Broadcom topics. Broken LZMA, broken Linksys device support,
broken BCM5358. I'll see if I can figure out sth from that thread.
