a53d451f30 o Ok, this seems to be a much better method for caching valid 
devices based on /proc/devices
   + The dev_mgr structure now has a 256 element char array that is
     initially all 0s
   + When a match is found, the array element corresponding to the major
     number of the match is set to a non-zero value
   + to check for a match, all one has to do is check that the array
     element at the major number in question is non-zero.
 o I'm wondering if we should do this with bitwise operators instead?  Does
   anyone expect the major numbers to grow larger than 8-bits?

9404455a07 dec use count on close. corrects a typo. 
Really the use counts on these modules should be handled at a higher level,
otherwise there are races I think.
