The ps2esdi driver was marked as BROKEN more than two years ago due
to being no longer working for some time.
A drivers that had been marked as BROKEN for such a long time seems to
be unlikely to be revived in the forseeable future.
But if anyone wants to ever revive this driver, the code is still
present in the older kernel releases.
