I don't think any of the DEC PDP-11 OS's support it. However I
vaguely remember someone (Megan?) saying she was running RT11 on
a DSSI disk. Perhaps the controller looks just like an MSCP
controller to the OS, just wasn't supported officially?

Someone with a reading knowledge of the BSD driver sources could
probably tell if the KFQSA is a totally different beast from the
RQDX/KDA/UDA or is similar enough that it has a shot at working.
