i would really like that too...the only reason i have qtlockscreen installed is to have one lockscreen in portrait, not rotating, but i don´t think its an ideal solution at least for me, as its one more app installed (two if you count the qtlockscreen configurator), and there is no skin to it developed so far that is maemo..ish...they all are just imitating other operating systems (iphone, android, etc.)...so i really like the maemo original lockscreen, just wish it rotates to portrait and stayed that way...anyone knows how?
