I believe you are mis-reading the partition table.  See comments
below.

No.  Look at the start and end numbers.  hda2 (the extended partition)
comprises hda5 and hda6.  hda3 and hda4 are primary partitions and are
not part of hda2.

No.  The problem is that all four slots in the main partition table
are filled, but they don't allocate all of the disk space available.
Cylinders 1-947 are allocated, but 948-1292 are not

1496849 is the size of hda6, not the last allocated cylinder of the
disk.

That is correct.

That is also correct, but, up until recently, not very useful, because
it used to be that logical partitions (parts of extended partitions)
were not bootable.

No, you have (in this order) one primary, one extended, and two more
primary, followed by two logical partitions that are made from the
extended.

No, it doesn't.  See the above.

That is more or less correct.

The rest of this is nonsense, and there is no cylinder 1496848.

There is a Partition mini HOWTO that is worthwhile reading.
