No.  Here is the mapping from SunOS:

        NULL,                   /* 14 = /dev/cgone */
        NULL,                   /* 26 = /dev/bwone */
        %DEVSW(bwtwo),          /* 27 = /dev/bwtwo */
        NULL,                   /* 31 = /dev/cgtwo */
        NULL,                   /* 39 = /dev/cgfour */
        %DEVSW(cgthree),        /* 55 = /dev/cgthree */
        NULL,                   /* 64 = /dev/cgeight */
        NULL,                   /* 67 = /dev/cgsix */
        NULL,                   /* 68 = /dev/cgnine */
        NULL,                   /* 102 = /dev/cgtwelve */

(never mind what those %devsw's are, just use the numbers :-) ).  The
indirect driver /dev/fb should be #22.
