Regression between uno and uno R2 VALIDATED. HARDWARE PROBLEM CONFIRMED

would the same apply to FT232RL driven chips?

No. But none of those seem to be exhibiting the problem...

can you explain why they wouldn't have the same problem?

have a look back at reply #53 from retrolefty (and the following couple of messages). he saw some aberrant behaviour from an Arduino board that had an FT232 fitted, it just took a little more digging to expose it. so the problem is not exclusive to the UNO, but in the case of the UNO R2 more obvious in its manifestation.
