Can I use ext2 or ext3 formatted external SD card in Android 2.1

If I insert an external sd card formatted in ext2 or ext3, will it be treated as a normal sd card (FAT32)?

The device is Samsung Galaxy S (Korean) running Android 2.1 I need the answer before I get the device tomorrow, because by the time I get the dev开发者_JS百科ice, I will not have any option to change anything in the card.

No. It does not work :( I tested on a real device (Samsung Galaxy S, Android 2.1) and found it out.

I found a hint of a solution here for rooted phones:
