Where are those registers stored?  Working registers are overwritten.
Preserved registers are saved somewhere on stack, but there is no
defined place where they are stored.  At least not on i386, ia64 has
unwind data that says where preserved registers are saved, i386 is all
ad-hoc storage with no way for kdb to tell where that storage is.
