please never ever do those 2 defines inside your module. the buildsystem
will add those automatic, and it gives a big mess if your module ever
goes to the upstream kernel

you have to set the task state like
set_current_state(TASK_UNINTERRUPTIBLE);
before you call schedule_timeout()

but you are far better off just using msleep().
(you are using a 2.6 kernel, right?)
