Hello,

> Does it scale? [...] Perhaps we may end up with a composite solution. 

If I had my way, there would be an extension to the e820 format to allow
the BadRAM patterns to be specified.  Since the extension with bad page
information is specific to boot loader interaction, this would work in
exactly those cases that are covered by the current situation.
