Some more information:

In sys/i386/i386/autoconf I'm seeing the following happen:

static void
setroot()
{
        int majdev, mindev, unit, slice, part;
        dev_t newrootdev;
        char partname[2];
        char *sname;

        if (boothowto & RB_DFLTROOT || (bootdev & B_MAGICMASK) != B_DEVMAGIC)
                return;
        majdev = B_TYPE(bootdev);
        printf("setroot: majdev=%d,bdevsw(majdev)=%p\n",majdev,bdevsw(majdev));
        if (majdev >= nblkdev || bdevsw(majdev) == NULL)
                return;
        unit = B_UNIT(bootdev);
        slice = B_SLICE(bootdev);

etc.

which prints

	setroot: majdev=4,bdevsw(majdev)=0

Thus the function returns, without setting the name of the root device further
on in the code (it would appear that that is where it happens).
