Additional info... this seems incredibly common to the Dell systems. All Dells I've tested so far exhibit this behaviour.
The upside is that I finally managed to get wireless turned back on on the Latitude 2120. The downside is that I had to reinstall the OS to do so.
For whatever reason, reinstalling fixed it.
So this tells me that using the hot-key to disable wireless sets a bit somewhere in the OS but from that point on, that bit can't be unset. So that may be a good clue where to start looking to resolve this, and it should resolve this issue across all the dells.
