I just tested this patch in -STABLE right now, and it's looking fine so far.

Plugging the eSATA box in triggers:
ada1 at ahcich3 bus 0 scbus3 target 0 lun 0
ada1: <WDC WD5000AADS-00S9B0 01.00A01> ATA-8 SATA 2.x device
ada1: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO size 8192bytes)
ada1: Command Queueing enabled
ada1: 476940MB (976773168 512 byte sectors: 16H 63S/T 16383C)

Playing an AVI with VLC off the external drive is fine, didn't do any 
more I/O tests.

Unplugging it (after unmounting) triggers:
(ada1:ahcich3:0:0:0): lost device
(ada1:ahcich3:0:0:0): removing device entry

Update of the gstat display is almost instantaneous, I see the GEOM 
providers appear and disappear when [un]patching.

Great job!
