It also might make more sense to move the checksum to after the inode
table, i.e., instead of:

Group 0: (Blocks 0-32767) [ITABLE_ZEROED]
  Checksum 0xe0c6
  Primary superblock at 0, Group descriptors at 1-1
  Reserved GDT blocks at 2-512
  Block bitmap at 513 (+513), Inode bitmap at 529 (+529)
  Inode table at 545-1056 (+545)
  24025 free blocks, 8181 free inodes, 2 directories, 8181 unused inodes
  Free blocks: 8743-32767
  Free inodes: 12-8192

how about:

Group 0: (Blocks 0-32767) [ITABLE_ZEROED]
  Primary superblock at 0, Group descriptors at 1-1
  Reserved GDT blocks at 2-512
  Block bitmap at 513 (+513), Inode bitmap at 529 (+529)
  Inode table at 545-1056 (+545), Checksum 0xe0c6
  24025 free blocks, 8181 free inodes, 2 directories, 8181 unused inodes
  Free blocks: 8743-32767
  Free inodes: 12-8192
