Is there a way to temporarily disable the touchscreen? I'd prefer to do this via one of the physical buttons if possible.
(In the course of my work, I'm often in relatively high RFI environments (but not beyond safe human exposure limits and often nowhere near such) which cause the touchscreen to start acting on its own (or sensing nearby objects as a finger touching the screen) and the phone becomes useless until I leave the area as it fights everything I do. I'm looking at replacing my 9800 with a 9810 or an entirely different device. While I'd like to stay with the Blackberry Torch line, I may end up moving to something different if this problem cannot be resolved.)

The issue isn't that I dislike using the touchscreen. The issue is that the touchscreen becomes overly sensitive and acts on its own when near more RF than just the phone. This happens all the time at cell sites and within a few hundred feet (sometimes more) of VHF and UHF radio transmission sites. It can happen with other RF/RFI sources as well. When the touchscreen is acting on its own, it is very hard to compose e-mail or make a phone call as it keeps 'touching' various parts of the screen. In order for the phone to be usable in these environments, the touchscreen needs to be able to be disabled. I am not accidentally touching the screen, it is acting on its own, hypersensitive.

Yes, I actually understood your situation from your initial post. As stated, disabling it completely while leaving the trackpad useful is not possible; you have to disable the entire phone by locking it or just use the trackpad (which is no good to you because your touchscreen will still get "used" by the surrounding frequencies).
Using one of my two suggestions or getting a phone that uses a physical keyboard are the only two solutions to your issue.
