Partitioning Steps for 2.0.9 final :
1) if you've previously partitioned your sdcard, you need to delete all your partitions first.
2) create partitions > a) FAT32  ;  b) EXT2 or EXT3 - not more than 2GB  ; c) Linux Swap - not more than 200MB - ALL PARTITIONS MUST BE PRIMARY.
3) format your sdcard using your computer
4) insert back your sdcard and it's all done.

1) & 2) as above
3) as above except c) Linux Swap which is optional. If you've a slow sdcard, i.e. below class4, it's not necessary to create this partition.
