I downloaded the bootstrap.dat file from the torrent at http://sourceforge.net/projects/bitcoin/files/Bitcoin/blockchain/ and placed it in the .bitcoin directory of a new Ubuntu installation of Bitcoin-Qt, ran the client and waited for the client to sync. In the blocks directory there are now blkxxxxx.dat files.
I expected the first 285 bytes of blk00000.dat to look like the ones at http://james.lab6.com/2012/01/12/bitcoin-285-bytes-that-changed-the-world/ complete with message about the Chancellor, but instead my first 285 bytes start with:
00000000 f9 be b4 d9 d7 00 00 00 01 00 00 00 6f e2 8c 0a |............o...|

00000030 1e 4b a7 44 bb be 68 0e 1f ee 14 67 7b a1 a3 c3 |.K.D..h....g{...|
and there's no readable text, i.e. no timestamp message from Satoshi. The magic number is there, but the rest of the data doesn't look like the genesis block.
Note that I'm using the standard Bitcoin foundation's client, and the genesis block has to be there for it to work (see How did the first 50 Bitcoins come into being?) so:
What am I missing?
