OK, I tested this against a fresh kernel tree, not once but 4 times.
I'm not sure why people have had problems applying this.
This also fixes some slight spacing issues - if(x) vs if (x) ...
This doesn't fix the problem with IDE spinning down on reboot, but it
does fix what could potentially be problems with very low power suspend
levels in the ACPI code.
