Dilog DQ132 question

Hey folks. I'm trying to get an Overland Data OD3610 drive
working with a Dilog DQ132 controller in a PDP-11/83 running RSTS/E.
The DQ132 manual documents dipswitch S8 as enabling 22-bit
addressing, and it defaults to disabled. Here's the relevant
paragraph from the manual:
Switch S8 selects between 18- and 22-bit addressing. Only the
TSV05 software handler supports 22-bit addressing on the Q Bus. The
TS11/TU80 handler may require modifications to support 22-bit
addressing on the Q Bus. Default value is S8 ON, selecting 18-bit
main memory addressing.
So am I to assume that it can be used as a TS11 in a 22-bit
system, and the driver uses bounce buffers? Any idea?
