No idea about the HAL end of things, but if you can figure out how to
get it to issue arbitrary commands when devices are attached, you could
echo the scheduler you want to /sys/block/whatever/queue/scheduler
I forgot to mention that I already used that method to change the
scheduler for testing. It works fine, but I was looking for an automated
method. hald already responds to the hotplug with a mount. It knows the
device information, so if I could just make it smarter.
