Hi Clive,
Do you happen to have an xorg.conf? if so, please remove it.
Xorg should probe for your screens and not need an xorg.conf.
It shouldn't need any kernel parameters passed.... But stranger things 
have happened!

Please post your xorg.0.log, just curious to see if the edid is read 
correctly.

FYI, I tried it with a Quadro FX4500 and a flashed GeForce 7800 and D.H. 
seemed to work.

I used a Dell 24" LCD @ 1900x1200 together with an old Philips 20" @ 
1680x1050 and it worked... For me anyway....

I should have an old GeForce 6600 laying around. I believe you mentioned 
this is GPU you have?
If you like, I can try it out when i get a spare moment as well to see 
if it works on my end.

It may end up being something specific with the GeForce 6600.

Keep us posted.

Regards,
Peter
