NetBSD alpha
>Description:
	The NetBSD Alpha Xserver fails to get interface configuration
	and causes unaligned accesses in the function DefineSelf in
	xsrc/xc/programs/Xserver/os/access.c.

Getting interface configuration (4): Device not configured

... repeat over and over ...

	Other problems still exist for -current with this Xserver...  but
	the following fix reduces the noise.
	More fixes to come...  mi wscons input module work in progress.

>How-To-Repeat:
	Build alpha Xserver...  run it...  watch it fail in multiple ways.
>Fix:

Fix for access.c: give ioctl the unsigned long it's expecting.
