These blobs are released by the OLPC project, and drive Marvell
libertas chips. OLPC hardware has additional features and quirks,
which makes special firmware necessary. The 'lbtf' blobs are
thin firmware, which allows the Linux drivers more control over
the device's functionality.
The firmware was downloaded from
http://dev.laptop.org/pub/firmware/libertas/.
