I guess that answers my question regarding why cacko 1.22 included an older version of the browser. It sure seems to me that there's enough to fix that it should be easy to make an improvement from 7.25 to 7.55. Unfortunate.
Does anyone know how to adjust the cache of opera so that it doesn't leak memory until it has to be closed and restarted? I assume that's where all the memroy is going, anyway. The blank page loading thing is annoying, too. At least it makes much better use out of a small screen than netfront.
