>Description:
	The raylink driver dev/pcmcia/if_ray.c is not big-endian aware and
	fails on big endian systems. The problem is the ray_read_region()
	and ray_write_region() functions. The problem lies in the optmised
	cases where the code tries to use 2 and 4 byte variations of
	bus_space_read_region and bus_space_write_region.

>How-To-Repeat:
	Build PCMCIA support and the raylink driver on a big-endian system
	and watch it fail the self test.
>Fix:
	My simple fix was to add ifdef's round that code that does the
	optimised transfers so that on big endian systems these functions
	always use bus_space_read_region_1() and bus_space_write_region_1().
