The work around I initially tried was to parse /proc/cmdline and map
'root=[0-9a-f]+' to a device. I didn't really like doing this, so I
just backed out the df change as a patch to my buildroot.

I hadn't noticed this with coreutils 6.9:

$ cat /proc/mounts
rootfs / rootfs rw 0 0
/dev/root / xfs rw,sunit=512,swidth=1536,ikeep,noquota 0 0
/proc /proc proc rw 0 0
....

$ /bin/df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/md0              2.1T  1.9T  194G  91% /
/dev/sda1             130M   41M   82M  34% /boot
...

$ /bin/df --version
df (GNU coreutils) 6.9
