Possible fix

I,am running Gentoo on Toshiba Sattellite L20-183 with ati x200m (RS410) and Pentium M 760 onboard. Machine cannot resume from suspend getting hard locked-up. I have to turn it off by pressing power button. 
There is nothing inside the logs.
Previously passing "nomodeset" parameter to kernel worked. Now, when ati Xorg driver cannot be started without KMS, "nomodeset" method doesnt work anymore. 
I think that radeon driver needs a quirk to make machine resume from suspend.

With this patch applied to kernel tree Laptop can resume from suspend.
