Attempt to fix radeon driver crash on sequoia board
while running new arch powerpc 2.6.25 kernels

The patch for Xorg source code tries to fix X server
fore recognizing and correct mmaping of PCI resources
on sequoia board running new 2.6.25 kernels. This
README provides short instructions how to build the
fixed Xorg server on sequoia natively using ubuntu linux.

 - Get the xorg source, patch and build

	$ mkdir x-src
	$ cd x-src
	$ sudo apt-get update
	$ sudo apt-get source xserver-xorg-core xserver-xorg-video-ati
	$ sudo apt-get build-dep xserver-xorg-core xserver-xorg-video-ati
	$ cd xorg-server-1.2.0
	$ ./debian/rules patch
	$ patch -p0 < xorg-sequoia-fix.diff
	$ ./debian/rules build
	$ sudo cp -v /usr/bin/Xorg /usr/bin/Xorg.orig
	$ sudo cp -v obj-powerpc-linux-gnu/hw/xfree86/Xorg /usr/bin/Xorg
	$ cd ..

 - Now build radeon driver

	$ cd xserver-xorg-video-ati-6.6.3
	$ ./configure
	$ sudo cp -v /usr/lib/xorg/modules/drivers/radeon_drv.so /usr/lib/xorg/modules/drivers/radeon_drv.so.orig
	$ sudo cp -v src/.libs/radeon_drv.so /usr/lib/xorg/modules/drivers/
