quick fix for 2.6.34 problem with serial synths

[Steve Holmes]

I also just tried to run my Speakout serial synth and got errors
similar to what others have been reporting.  I will paste in the most
relevant line from the system log.
Trying to free nonexistent resource
<00000000000003f8-00000000000003ff>
Before that, tynth probe was followed by being unable to get the port
and "trying to steal them."  I got the same results with talkwith and
manually trying to do echoing to speakup/synth.

In any case, the pride and joy of Speakup with serial synths doesn't
work for me either.  This happened with both the binary version on
ArchLinux and the git pull from just an hour ago (July 6th).
