Errrk.  My Gig disk has something like 1004 cylinders, which is very
handy.  I have no problems with placing operating systems anywhere on
the disk.

According to the documentation you have just quoted, yes.
However, this does *not* mean that it must be a primary partition.
If that were to be true, then no disk with less than 1024 cylinders
could have extended partitions.  This is evidently not the case.

Primary and extended partitions can actually live at any position on
the disk (as far as I am aware).  However, as you have discovered
there are limitations on what you can do with those partitions
(primary or extended) that are on cylinders greater than 1023.

[...remaining questions snipped...]

Sorry, I don't have answers for these questions.
