I presume he meant a difference in opcodes between the 8088 and V20.
Didn't the V20 have some additional operations available to it?

It was thus said that the Great Fred N. van Kempen
once stated:
Yes, we had
this in Minix to test for V30/X86. Cant member what
the V20/X88 was, probably a missing opcode.
I don't think there were any opcode difference between the 8086 and 8088,
but there was a prefetch queue length difference that was easily testable
with some self-modifying code.
