Subject: [PATCH] radeonfb supend/resume support for Acer Aspire 2010

Hi Ben,

the patch below has been tested by Benjamin Okopnik and makes
suspend-to-RAM work for him perfectly on his Acer Aspire 2010.
Without this patch, a total lockup happens on resume.

I hope the patch is still in the merge window for 2.6.19.

Regards,
Carl-Daniel
