If EDD is detected and doesn't work, we're kind of operating in a "the 
system is exceptionally screwed" mode already.  If the sector size then 
isn't 512 then we're so far down the creek it isn't funny.  I really 
don't care what happens then... most likely assuming 512 makes sense, 
because the sanest option is that the EDD detection was false and in 
fact we don't have EDD and the sector size returned was totally arbitrary.

That is the problem with dynamic detection.
