The "more aggressive scan" relates to the "I=TEST" option only. In v5.80, it does what is documented, in previous versions it only scanned "external" ROMs ( the VGA ROM, for example ).

X=TEST is not really useful on "modern" systems, since jemm ignores automatically all regions defined as reserved ( via BIOS call int 15h, ax=E820h ).
