Touchpad crashes Compiz not with external mouse though

[Porksome]

I have rather strange problem.

I am running the new 7.11 fglrx with compiz on Radeon 9600 M10 and it works beautifully. However I am only able to use compiz with an external usb mouse attached. If I attempt to start compiz with only the touchpad or remove the external mouse while compiz is running the whole system instantly freezes and can only be restarted using Alt-Sys Req-S U B

This is baffling me. Is there a parameter I should be passing to compiz (using 'compiz --replace && emerald --replace' to initialise).

Thanks
