right :)
this is the tested version (call it V2 if you wish), against 29-rc2 and 28-

I still have no idea what those quirks really do, so test before including

Subject: [PATCH] libata-pmp: add support for Thermaltake BlackX Duet esata drive dock
some errors still show up, but the dock works, both drives can be
accessed at the same time
the chip maker and designation is unknown - possibly jmicron JMB350?
