//bugs.freedesktop.org/show_bug.cgi?id=1962) attachment #1423
(https://bugs.freedesktop.org/attachment.cgi?id=1423): Avoid PIO access
on IA64. Some IA64 machine check if legacy ports outside the VGA range
are accessed. The ATi driver however does this to probe for ISA
Mach8/32/64. Since no IA64 has ISA slots this restriction should not be
relevant to the user. Patch by Egbert Eich <eich@freedesktop.org>
