That sounds like the right solution for now, yes.  Rather than make
the readback quirk depend on one particular SMBUS revision, make it
happen unconditionally for an AMD northbridge (or is the HPET in the
SB? I forget - somebody who knows the details and can test it on a
machine or two should do the actual patch).
