It does appear that the source voltage has been recently changed. I just picked one of these up and the voltage was sourced from the 3.3V pin. This is also referenced in the current schematics.
I was not able to get it working on an Arduino Duemilanove using the FAT16 library with a Kingston 512MB card. It is working using the SdFat library after changing the Sd2Card.h to #define SOFTWARE_SPI and changing the 3 SOFT_SPI_SS_DDR/PORT/BIN pins from PIN10* to PIN8*.
Its also worth noting that the minimum sketch to open a file and write a string is 2K smaller with the SdFat lib.
No public wish lists :(
