"part list" prints partition UUIDs (from the partition table), whereas I 
/think/ blkid prints filesystem UUIDs (from the fs superblock).

The kernel will accept either on its cmdline root= parameter, but you 
have to tell it which you're using, e.g. root=PARTUUID=partition_uuid, 
or IIRC root=UUID=fs_uuid.
