I look at the raw stack data from time to time, but mostly I want the backtrace, PC and LR converted into something more meaningful, and I don't want the extra clutter of that particular raw data.

Not so. This is my point; on the ARM, when you get stuff like stack and registers dumped, a lot of the hex numbers can look very much like addresses in kernel space; most of them are data object symbols and the like. There can be a lot of these, and suddenly you'd end up with most of the System.map being output because something in the dump somewhere looks like its a symbol.
