Hmmm. The device will be detected then, but the driver is still built-in
and its init function should therefore still run when the init calls are
processed. It's a question of probing vs. just being built-in.

That's a different issue. That's waiting on enumeration, which is not
correctly handled at the moment IMHO (without udev hack jobs). And
rootdelay is widely regarded as a huge giant ugly hack :-)
