Yes I'm a bozo.  I just sent a reply with no new text.  Sorry.

There are efforts underway to solve this problem in multiple ways in
amanda.  One that's actually in released code is a RAIT function.
Of course that's not most folks favorite solution, but someone found
it useful enough to actually do the work.

There was also a patch sent in recently that splits selected dump files
into chunks, which is analogous to the split solution someone else
suggested here.  This is not in release code yet, and I don't believe
it's release-ready yet, either, but enough of the coding is done to
prototype it.

If you tell me what problems you had or are having, I can hopefully
help.  If nothing else I'd like to know what you found difficult so
I can improve the rather lame documentation.
