Maybe you could add a note:
(Note: for POSIX support lower 'm' is allowed for "MiB", but is not recommended)
(Note: In contradiction to SI, lower 'm' is allowed for "MiB" for POSIX support, but could become 
deprecated)

Then user would not try other lower letters if coming from FAQ tips like:
ntfsclone -s -o - <source> | gzip -c | split -a 3 -b 700m - <destination> ,
... and FAQ tip authors are aware to better use 'M'.
