Not always. I was supprised when I ask for a "Pop Up" from Toledo, OH
the other day. I ask for a GPS approach and he ask if the plane was
IFR GPS equiped and current. I guess because there are so many VFR
GPSs. I said yes and that was that.

This caught my eye the other day:

!FDC 5/2548 FWN FI/T SUSSEX, SUSSEX, NJ.
VOR OR GPS-A AMDT 5B...
PROCEDURE NA EXCEPT FOR IFR GPS-EQUIPPED AIRCRAFT.

I struck me as strange that they felt the need to explicitly state "IFR
GPS" for an approach procedure. And, even then, it's badly worded, since
there are plenty of IFR GPS units which are not approved for approaches.
