It's quite confusing until you figure out what it's doing. I'm still
not understanding how dos/win names partitions :-)

There may only be four partitions on an IDE drive. These are the
primary partitions. To get around the four partition limit, you can
make one of the primary partitions into an extended partition.
Within this extended partition you create logical partitions. To the
BIOS (and early versions of DOS) these logical partitions do not exist,
they're just one big primary partition.
So if you have 2 primary partitions, 1 extended partition, and 3
logical partitions, the BIOS sees only 3 partitions, but Linux or
Windows sees 5 partitions. The extended partition is not seen since it
is only there to hold the logical partitions.

It should be the same partition. Write down the sector start and end
assigned to it in DOS fdisk, and check that they're the same in Linux
fdisk.

Yes, but two of them need to be logical partitions:
hda1 <primary> - windows C:
hda2 <primary> - windows D:
hda3 <primary> - linux /
hda4 <extended> - not seen by anything but fdisk
hda5 <logical> - linux /usr
hda6 <logical> - linux swap

I'm not sure what the 2.2 limit is, but 2.0 has a limit of 128Megs.
