O.K. as a first step i'll limit 5210 code only then, just an option
like "support older 5210 chipsets" which is going to be off by default
instead of 3 options. It's not just saving space, it's also saving
some runtime checks. It's not really a gain in performance though,
most checks are done during initialization and dfs setup, i just
thought it would be usefull to save as much cpu as possible.
