I'm surprised to hear of your problem with light bulb longevity. I have a number of ordinary incandescent light bulbs connected to X10 wall switches and lamp modules. They're on daily from dusk to dawn, dimmed about 10% from max, and only rarely need replacement. I think some have been running for 2-3 years or more.

What's the usual power line voltage at your house? (Mine usually runs between 120-125 V.)

Your experience with bulb longevity on X10 dimmers is exactly opposite to mine. Certainly vibration can be a big factor with any incandescent bulb and there have been reports of noticeable "buzzing" with some lamps on dimmers.

Could your experience have anything to do with bulb orientation? Most of the lamps controlled by X10 dimmers at my place have the bulbs in socket-side down orientation. I know that some bulbs are rated only for socket-side down or horizontal orientation, and wonder if perhaps _all_ bulbs are more susceptable to earlier failure if operated socket-side up. I assume the difference has something to do with the effect of heat on the glass-metal seal where the wires go through the glass.

BTW, most of the X10 wall switches and dimmers at my place are Radio Shack branded and were installed ~ 1997. One wall switch failed and was replaced about 2 years ago. Lighting is controlled primarily by timed macros and remotes - wall switch push buttons are rarely used.

Unless you have some very weird power situation (which I can't imagine), the only other thing I can think of is vibration - either external or some self-resonance of the filament. Have you tried different brands or styles of bulbs? (Clear bulbs let you see how the filament is mounted and it can vary markedly.)
