I've been using GV 2.2 since Saturday night (with mods as below). All seems fine, except that it seems that the USB data connection doesn't work with EViollet's kernels (not tried, but it's been confirmed by a number of people). Problem is specific to these 2.6.35-based kernels - USB transfer works with GV kernels or Vork (tested that one myself, good transfer speeds) - and the dev is aware.
