Bugzilla Bug 228423

originally I had the problem that the radeon drivers did not work at all see
(http://forums.gentoo.org/viewtopic-t-696022-highlight-.html)
so i installed some testing packages.

x11-base/xorg-x11 ~amd64
x11-base/xorg-server ~amd64
x11-libs/libXrender ~amd64
x11-proto/renderproto ~amd64
x11-proto/xf86driproto ~amd64
x11-proto/videoproto ~amd64
x11-proto/xproto ~amd64
x11-proto/glproto ~amd64
x11-drivers/xf86-video-ati ~amd64
x11-drivers/xf86-input-keyboard ~amd64
x11-drivers/xf86-video-vesa ~amd64
media-libs/mesa ~amd64

that's while updateing xf86-video-ati I got a compiling error.

X_BYTE_ORDER is not defined properly.
in file /usr/include/xorg/xorg-server.h line 200 there is a problem. The accual
error is in radeon_accelfunc.h but the problem is there.

/*#ifndef __APPLE_CC__
#define X_BYTE_ORDER _X_BYTE_ORDER
#else
#ifdef __BIG_ENDIAN__
#define X_BYTE_ORDER X_BIG_ENDIAN
#else
#define X_BYTE_ORDER X_LITTLE_ENDIAN
#endif

I don't know how these lines should be correctly, so I took them out all
together.

and replaced them with what was there in earlyer xorg-server versions.

#define X_BYTE_ORDER X_LITTLE_ENDIAN

now it works like a charm.

Reproducible: Always

Steps to Reproduce:
1. normal gentoo system
2. add testing packages from above to /etc/portage/package.keywords
3. and emerge -uND world
