Hey Ralph!,
I saw the update yesterday also! They had already sent an e-mail to me saying that they have the display on stock again.
I'm a little bit afraid of buying it from internet. They only shipment way is with "Standard Registered Airmail" to Brazil and our customs are an huge mess! It can take more than a month to arrive at my home.
At Least Nokia anounced this week that they will bring the N900 in about 60 days! Which means that brazilians will have replacement parts!
Just an information: Sometimes when I twist the N900 my "crack" seems to have became worst. I think it's not a nice signal. Now, my huge black spot has just became white for example.

Keep us informed, Ralph.
cheers,
Lucas Kok
