Ah ha! there in lies the problem. The reason you were getting a clone mode was because the videoram option overrides the size of the video ram detected by the driver. When you use xinerama, it divides the video ram into two framebuffers; one for each pScrn (effectively giving each head half of the video ram). Specifying videoram may override what was allocated to each head resulting in some sort of undefined behavior, hence the clone mode. if you are using a newer rawhide build, you should get the screen blanking bug, that was fixed. You also won't see it if you are using a sw cursor. Just a suggestion for users out there, you really don't need to specify videoram for any of the drivers as a general rule. the memory detection routines, in my experience, work about 99.999% of the time.
