+Sure? yes and no ;-) Both locking and unlocking (for Write modes)
+involves copying memory (using same function).
+
+The problem seems to be located between r60839-60877. Gonzalo made
+some fixes that, I suspect broke the 24bpp mode. I'll ping him to see
+if he recalls why the changes were required.
