 I suspected as much, but there's the second (first) part to this
 problem too.
 
 On NetBSD-6 modload name and modload path behave the same:
 
   nb6# modload nand
   modload: File exists
   nb6# modload /stand/i386/6.1/modules/nand/nand.kmod 
   modload: File exists
 
 On 7 and later modload name fails with EEXIST right away without
 actually trying to load the module.  But modload path does try to load
 the module (which causes bad things on 7 and is caught by the kernel
 linker on 8).  Shouldn't modload path detect EEXIST without trying to
 load the module too, like it did on 6?
