I really am only attempting to create 3 partitions as per the scheme
shown in the original mail.  Yet still it will want to make the final
partition logical:

/dev/sda1   *           1        1009     8104761   83  Linux
/dev/sda2            1010        4297    26410860   83  Linux
/dev/sda3            4298        4425     1028160    5  Extended
/dev/sda5            4298        4425     1028128+  82  Linux swap

re. number 3 - I ended up writing a perl script which duplicates the
calculation quite happily.
