Was about to update my rom today to hashcode's latest with the deep sleep fix, however for some bizaar reason (though nothing has changed since I rooted it) the kindle will not connect to my computer, thus allowing me to access it to copy the files across.
edit:
Fixed it in recovery, though I am a little concerned that i can't mount it in normal operation to transfer books/music e.t.c..
