Shortened quote from FSF website:
"The BeagleBoard (various versions) uses the TI OMAP family of SoCs... The
graphics accelerator (GPU) and the video decoding hardware for formats such
as MPEG-2 are nonfunctional, because they require nonfree blobs to be
installed into them. The workaround for these flaws is to do these jobs on
the CPU with free software."
So, maybe a BeagleBoard Black could potentially get a FSF approval, e.g. if
these jobs will be transferred to CPU by default, but this could greatly
decrease a performance of this already-not-so-fast board
