20080620_Xorg_nouveau.log

After forcibly changing the le{16,32}_to_cpu definitions to do the
bswap{16,32}, here's what happens.

The full Xorg.log is attached, but the snippet at the end that catches my eye
is:
(II) [drm] DRM interface version 1.3
(II) [drm] DRM open master succeeded.
(II) NOUVEAU(0): [drm] Using the DRM lock SAREA also for drawables.
(II) NOUVEAU(0): [drm] framebuffer handle = 0x98000000
(II) NOUVEAU(0): [drm] added 1 reserved context for kernel
(II) NOUVEAU(0): X context handle = 0x1
(II) NOUVEAU(0): [drm] installed DRM signal handler
(EE) NOUVEAU(0): Failed to allocate memory for framebuffer!
