Updated fglrx patch for ATI Radeon and Xen

hi,

I've cleaned up the patch and updated it to work with the latest 8.10.19 
version of the ATI driver. I've tested it on Gentoo with xorg 6.8.0-r5 
(just change the ebuild to apply this patch after the other patches in 
src_unpack()) and seems to work fine, including OpenGL acceleration.

I was unable to get fglrx working with xorg 6.8.2, because they changed 
to format of the driver modules from .o to .so. Attempts at hacking 
around this (converting the fglrx X module to .so by hand) were 
unsuccessful.

The patch is attached.

Best regards,
Jacob
