the device manager is initialized. For x86 it does nothing, but for PPC it searches for a supported interrupt controller and remembers it for later use. arch_int_{enable,disable}_io_interrupt() are implemented as well as handling of external exceptions (aka as I/O interrupts). We'll see later how well that works. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16271 a95241bf-73f2-0310-859d-f6bbb57e9c96
