Good point, trag.
However, just checked the SE/30 schematics and its FPU's /CS signal comes directly from the GLUE chip, and nothing else is connected to it, so that one won't be disabled.
Also, from the IIsi PDS/030 slot specification, I can't see anything directly related to the FPU, so it should be decoded somewhere into the adapter's logic. Still, there's the problem of choosing the appropiate value for this pull-up resistor...
