So… you finally decide to search in google about this problem, it took me 5 tries, before doing it.

So the short answer… the image for mysql is UDF, and appears like the UDF driver is still 32 bits, and I guess if you are here, is because you are running on the 64bit kernel…

Well this is the price for early adopters, you have to boot in 32 bits kernel to be able to mount it on snow leopard

Long history, and a linux workaround (?):
