I will commit your patch, since it is easy to revert. The avision
backend author may be able to comment further on the status.

Well, in this particular case I think the sp15c backend probably
supported these Avision-built Fujitsu machines better at one time, but
that driver is unmaintained now. On the other hand, the avision
backend supports a huge number of machines, so unintended regressions
can sometimes be a problem.
