 That looks all fine, so it should actually work.
 If you look into src/sys/arch/x86/x86/x86_autoconf.c, you will find the
 function findroot().
 Inside you will see
 
        if ((biv = lookup_bootinfo(BTINFO_ROOTDEVICE)) != NULL) {
 
 and a loop over all disk devices that actually did attach. I would
 suggest adding a few printfs there to see progress and find out why it
 does not pick the (apparently properly matched) device. Look at the
 strncmp and print both device names at least.
