Default Base mosaic and rotation?

For reference, I have two cards and four heads in a line from left to right: landscape, portrait, portrait, portrait. I am currently configured in base mosaic mode to make all the displays active.

I'm getting this in my Xorg log:
Code:
[ 29737.755] (WW) NVIDIA(0): Rotation and Reflection are not supported in this X screen
[ 29737.755] (WW) NVIDIA(0):     configuration: ignoring Rotation and Reflection MetaMode

[ 29737.755] (II) NVIDIA(0):    
[ 29737.755] (II) NVIDIA(0):     "GPU-0.DFP-0:nvidia-auto-select,GPU-0.DFP-1:nvidia-auto-select{Rotation=left},GPU-1.DFP-0:nvidia-auto-select{Rotation=left},GPU-1.DFP-1:nvidia-auto-select{Rotation=left}"
Should I interpret this as rotation not currently being supported in base mosaic mode? If so, why? Will this magically work if I locate some SLI cables, hook my two cards together, and switch to SLI mosaic mode? I may have to downgrade to 295 and restore my old Xinerama-based config if I can't get this working adequately.

Getting driver 302 was a mostly pleasant surprise this morning: although my computer is now basically unusable because I don't like turning my head 90 to get work done, it's nice to know that XRandR 1.3 is finally (mostly) supported. Good job, devs.

The only other obvious problem I've noticed is that the output of xrandr --current makes no sense: it lists four DVI devices, but only two of them (DVI-I-2 and -3) are active and have resolutions while the other two (DVI-I-0 and -1) are listed as disconnected. This, despite the fact that all four heads are working. So there may be some integration problem here.
