If you have more devices, this single parameter will affect all of them. That's not a good approach, especially when the value you are trying to change can be changed on the fly. I understand the problems you have with tx power control, but modifying a stack because of a buggy driver (I know it's not your nor anyone else's fault and nothing can be done with this now) isn't a right way to go. The correct approach is to write a new rate control module. Note that this should be still understood as a temporary solution, as you have no factual reason for depending on a specific rate control module. See the following patches. However, I'm not against setting the initial value to the lowest rate available. As Johannes pointed out, if the rate control algorithm isn't able to quickly migrate to higher rates, it's a good candidate for rewrite.
