Does someone Swap S5570?

[windfeng998]

I've tried many times to swap my s5570. All failed. The message showed:
swapon: /dev/block/mmcblk0p3: Function not implemented.

My ROM is Froyo.ZSKD2. (Android 2.21)
My SD partition showed as below:

Anybody made the Swap success?
Does this ROM not support Swap?

Please teach me.
Thanks,

Seems 2.3.4ROM didn't support EXT partition. Link2SD doesn't work.
