I dont think its possible... People prefer QWERTY keyboards in SoftIce, as its easy to type commands with one hand, and scroll the code with another.
Anyway, Why waste time with softice? its a discontinued product, and its buggy as hell with windows xp and vista, and there are MUCH better debuggers than it. You can try OllyDBG. Of course, if you are debugging ring0 programs, its not much of a help.
