Basically they didnt show up because _only_ Fujitsu/Siemens use that paticular
weird memory layout. You need a fairly specific setup where SMM mode
code that uses EBDA space.
Free software is good at being reliable - but its a testing/review/fixing
scheme that is nothing like as effective at finding situations where the code
works for everyone currently but isnt quite to specification.
