Here what I did
1) Kernel

/usr/src/linux/drivers/char/drm/radeon_cp.c

comment out
/*
#if defined(__alpha__)
# define PCIGART_ENABLED
#else
# undef PCIGART_ENABLED
#endif
*/

#define PCIGART_ENABLED

and then I got drm works

But I don't think I have to do that, but I don't know  because I am
too lazy to make a new kernel without that feature, after I got Xfree86
work with glx.

Herewhat I did:

1) download 4.2.1 source code from Xfree86.org
2) modify xc/programs/Xserver/hw/xfree86/drivers/ati/radeon_dri.c
comment out

#include "sarea.h"
/*
#if defined(__alpha__)
# define PCIGART_ENABLED
#else
# undef PCIGART_ENABLED
#endif
*/
/* insert this line */
#define PCIGART_ENABLED

/* ?? HACK - for now, put this here... */
/* ?? Alpha - this may need to be a variable to handle UP1x00 vs TITAN */
#if defined(__alpha__)
# define DRM_PAGE_SIZE 8192
#elif defined(__ia64__)
# define DRM_PAGE_SIZE getpagesize()
#else
# define DRM_PAGE_SIZE 4096
#endif

/* insert this line */
#define DRM_PAGE_SIZE 8192

3) modify
xc/programs/Xserver/hw/xfree86/os-support/linux/drm/kernel/radeon_cp.c

/*
#if defined(__alpha__)
# define PCIGART_ENABLED
#else
# undef PCIGART_ENABLED
#endif
*/
/* insert this line */
#define PCIGART_ENABLED

4) Last one this I trial and error, some how it works. According to
Whitney.diff patch.

Try it and let me know if you have any questions, I would like to know the
result too.

Thanks,
