Ah that was apparently your actual need rather than limiting the number of 
drivers per-se. Do you have profiled where time was lost if you find opening 
too slow ? The identification logic of drivers is supposed to operate fast 
(extension based, or on the content of the first kilobyte of the header), but 
there might be some drivers where improvements can be done.
