So it's still buggy, but much less buggy than before. I recently upgraded to KDE 4.11.1 (using KScreen 1.0.71) and now the display settings seem to get applied much sooner in the login process -- before any other applications get loaded, in fact. So lately I haven't been able to reproduce this problem.
