According to Rick's reply in this thread a damaged row in a DIMM can
easily cause a few thousand entries in the e820 table because it doesn't
handle patterns. So the question I'm asking is, is it acceptable to
have an e820 table with thousands maybe ten-thousands of entries?
I really have no idea of the implications, maybe somebody else can
comment on that.

Given that that is what actually ends up happening in the kernel at some
point anyway, 

hwpoison can poison most pages without any lists.  Read Stefan's original patch.

The only thing that needs list really is conflict handling with
early allocations.
