I think that you can measure the charge to mass ratio of the electron using the cathode ray tube method. I think the mass is the gravitational mass in that case.

This would be inertial mass. The force is electrostatic, F = q E. The resulting acceleration and deflection would give inertial mass.
My thought is to modify this experiment to balance the electostatic force with gravity, m g - q E = 0 and no deflection. If it can be done, then the electron has a gravitional mass. Of course, you would need a really long CRT.

I'm sitting here grinning like a fool, envisioning such a long CRT...
Seriously, though... The CERN and other groups do a lot of work accelerating electrons and positrons... Do they have to correct for gravity?
(At one point, weren't people seriously considering the possibility, however vastly remote, that antimatter was also antigravity? IIRC, they took a long time to create enough antiprotons to demonstrate that antimatter was attracted to ordinary masses.)
There is a difference between "pseudo-science" and a "dumb guess."
