I have two problems with this patch. First, it seems to break my amr
device which is no longer able to probe disks. Backing out this commit
fixes the problem.
Secondly, with WITNESS enabled my console is full of the following
errors on boot:

It's not legal to call bus_dma_tag_create with locks held.
Thanks,
Jeff
Also, it seems to panic my machine. Can't confirm though, and since it
was during a installworld my machine is too botched to do anything but
reinstall. The panic string is: Too many DMA segment entries and the top
of the backtrace, before the call to panic() is a call to
ata_setup_interrupt(). Can't get further though as the system is totaly
botched.
The controller is a intel AHCI one. I also got the same LORs as Jeff.
Regards!

Add experimental support for SATA Port Multipliers
Support is working on the Silicon Image SiI3124/3132.
Support is working on some AHCI chips but far from all.
Remember this is WIP, so test reports and (constructive) suggestions
are welcome!
