Uhm, "raw partitions" is a bad term; 'un-blocked interfaces' perhaps is clearer?

RAW_PART (see above) is defined in places like this:

./arch/i386/include/disklabel.h:#define RAW_PART        3
               /* raw partition: XX?d (XXX) */

./arch/alpha/include/disklabel.h:#define        RAW_PART        2
	       /* raw partition: xx?c */

So, having learned alot about the "BSD way" of lseek versus vnodes,
can anyone explain to me why we don't do bounds-checking on RAW_PART in
cdstrategy/sdstrategy/etc.?

[Also, should we note in the pax(1) man page that one wants to use !RAW_PART
when writing to / reading from a device whose strategy routine behaves this
way?]
