[Linux-ia64] poweroff through ACPI does not work on 2.5.60 ia64

[Xavier Bru <Xavier.Bru@bull.net>]

Hi,

Unlike the 2.4.* version that provides poweroff for ia64 through ACPI (power
state S5), 2.5.60 only provides poweroff for i386 platforms through
acpi/sleep.c.
With the following (not so clean :-) patch, I could have it working on 
2.5.60. Thanks for providing a cleaner one.

Xavier
