What version of Linux are you referring to?  It's my understanding that
linux for x86 does it the same way NetBSD does it.  In fact, there was
discussion on the MkLinux list, and AFAIK, MkLinux DR3 will use the same
scheme.  The only difference is, of course, that the letter and number
serve opposite purposes and are backwards....
