Default --base-mosaic and 2x GT240

Dear all,

I am attempting to get --base-mosaic going for my two graphics cards. They are as follows:

damien@damien-desktop:~$ lspci | grep -i vga
01:00.0 VGA compatible controller: NVIDIA Corporation GT215 [GeForce GT 240] (rev a2)
02:00.0 VGA compatible controller: NVIDIA Corporation GT215 [GeForce GT 240] (rev a2)
It appears that they are not supported:

damien@damien-desktop:~$ cat /var/log/Xorg.0.log | grep EE
	(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
[  1152.174] Initializing built-in extension MIT-SCREEN-SAVER
[  1153.061] (EE) NVIDIA(0): Failed to find a valid Base Mosaic configuration.

[  1153.062] (EE) NVIDIA(0):     - Chipset not approved for SLI
[  1153.062] (EE) NVIDIA(0): Only one GPU will be used for this X screen.
The driver version is as follows:

Any tips?

EDIT: I have cross-posted this question at the new nvidia linux forum: I will attempt to get any useful information synchronised.
