I'd say it's less than 10% of the cards that make troubles with flag 256. It won't make sense to start lots of tests. Simply do the checks as it was suggested to be on the save side. No Sybixsus, it wasn't adressed to you. I was talking about end users.
A much more important question seems to be: will the support for this flag increase in future hardware (+ drivers) or is it gonna decrease.
