re: xsrc/50429: Xserver fails to start on Ultra-5 andNetBSD/sparc647.0

FWIW, i built kernels from 20141201, 20131201 and 20121201 and
they all fail with a netbsd-6 userland.  so what ever broke was
pretty soon after netbsd-6 branched.  i've also confirmed it is
*not* this change, at least it doesn't help netbsd-7:

revision 1.75
date: 2012-05-07 19:25:25 -0700;  author: macallan;  state: Exp;  lines: +3 -3;
don't enable IO access - we don't use it and at least on some macppc machines
the IO BAR contains garbage
should probably be pulled into 6.0


netbsd-6 branched on .. 20120215 it seems.
