As was already pointed, "removable" flag is set by kernel based on whatever 
information device returns.

That is probably a reason manufcaturers mark it as "removale", which is 
strictly speaking wrong. The basic difference (from HAL point of view) is 
that it must poll "removable" for medium presence, while "hotpluggable but 
not removable" do not need it. Actually Mandrake disabled polling for USB 
sticks long ago (using fdi).
