Thanks :) I was more than just a little intimidated by my first post to
LKML, and I wanted to make sure the first reply to my report wasn't that I
didn't have enough info, or that I presented it in the wrong way, or
hadn't done enough testing with it. I was also more than prepared to
wait weeks for someone to reply, so thanks for the quick return! :D
