... anyone upgrading from beta10a to beta11 without going through the IR fix kernel will still have "dodgy" IR.

I must have missed the 'IR fix', because it's definitely 'dodgy'. Can I jump back to b10a, and then install the 'button fix', 'IR fix', and then go to b11? By the way, where can one find the IR fix? (is it in that 'secret-squirrel decoder ring required' directory on the old web site?)
