sorry to bump an old thread, but i had this problem after updating my x10 mini from 1.6 to 2.1. i tried lockbot , no lock and widget lock and none quite cut it. in the end "antilock" did the trick. it skips the swipe and goes straight to pattern. only problem is you have to then unlock to see the time!
if only it could go to pattern unlock with home key and just show the clock with back key or summats...
