You've got a typo in the description on a key word, "cat".  Is it can't?  can?

I'm not convinced that this patch is valid.  My understanding is that
if a card receives a command it does not understand, it should not
respond.  Thus, if it responds with an error, it's an actual error.
Are you saying that some cards respond to cmd 8 that don't implement
2.0?  Because that would not totally surprise me, but would violate
not just 2.0, but 1.x, as CMD8 is reserved.  MMC cards should also not
respond to CMD8 at this stage in initialization, as they are in the
wrong state...
