I am running some tests today on the wl1283-st on the Logic PD Torpedo
board. Tony had suggested a few options, so I'm going to try those.
Looking at those today. If/when you have a V2, please CC me on it. If
it's been posted, can you send me a link? I would really like to see
the st-kim driver go away so I'd like to resolve the issues with the
torpedo board.
