For some instruction groups -- e.g., Groups 12, 13, 14 -- the instruction prefix (66, f2, f3) and the reg field both affect the instruction type. And for some x87 instructions, the value of the modrm byte's rm field also affects the instruction type. (For others, rm just selects among the st(0)..st(7) registers, as one might expect.) Of course, that's all about floating-point instructions, which are of more interest to uprobes than kprobes.
