Low-voltage dimmer switches in end-of-line boxes?

I bought a house a year ago -- it was built in the 1910s and updated in the 1960s with more modern wiring -- but still 1960s wiring.

I've put up halogen light fixtures in the dining room, kitchen, and both bedrooms. Now I'd like to put dimmers on those fixtures. I went to a local store and bought some Leviton Decora electronic low-voltage dimmer switches rated for up to 300W, which is more than any of my fixtures.

I pulled out the existing dining room and kitchen switches to check the wiring, and both of them are end-of-line -- the power runs to the light fixture box and then a single white-black-ground wire runs down to the switch.

These dimmers say that a white neutral wire is required. I know that it's not required on other switches, but I don't have experience with low-voltage dimmers.

Can I get away with no white neutral wire in an end-of-line configuration?

My guess is no. They wouldn't say one is required if it's not.

Are the fixtures line voltage (120V) or low voltage (12V)? If you already have them installed and working on line voltage, as your post seems to imply, they are line voltage. You would need a standard dimmer instead of a low voltage dimmer. Low voltage lights will have a transformer, and that transformer must be rated for a dimmer; sometimes they require a special dimmer.
