Yes, sorry.  My commit would fix the case where it was under SYSR (system
resource) _and_ FDC0.CRS (floppy current resources) but it turns out to be
missing there, as you found.  Try seeing how it works for you with just
adding the 0x03F0 line under FDC0 and not deleting it from SYSR.  (I just
want to be sure my resource code works for you, this is not a final fix.)

I'll look into what might be done with PRS and SRS for this device.
