 - I'm not sure we ever want to support floppy boot on sparc64 (even a
   realy stripped down kernel would be like 3 floppies)
 - I don't like the very loose way device names are matched:

        strncpy(bootdev, prom_getbootpath(), sizeof(bootdev) - 1);
        boothowto = bootoptions(prom_getbootargs(), bootdev, kernel, bootline);
+       isfloppy = strstr(bootdev, "fd") || strstr(bootdev, "floppy");
 
        for (;; *kernel = '\0') {
                if (boothowto & RB_ASKNAME) {


I don't think "floppy" will be ever visible here, and instead of "fd" we
should probably better check for something like "/fdthree" or "SUNW,fdtwo".
Even better would be testing on actual hardware - does anyone have a sparc64
machine with working floppy drive?
