The provider for my driver is the IOMedia for disk2s2 (it actually can
and usually does have more than one provider, but that's irrelevant
here), and the IOMedia nub my driver generates is disk3.

What do you mean by that?

You can do most things that you can do with user-space gdb. You might
also want to look at all the macros in kgmacros. Some of those are
extremely useful.
If you want to force your code to break to the debugger (e.g. in your
own replacement for assert()), use
__asm__("int $3");
(at least on i386/x86-64)
