I figure this is a Gentoo bug because obtest is not included with the actual
tarball from sf.net.
Normally, on my HP ze4560us, this command will turn off the mute led:
obtest -k 0x94
But it now segfaults. Strange thing is that it happens with the old version as
well. Might be some other package that broke it but I can't pinpoint it. This
is the strace:

Reproducible: Always
Steps to Reproduce:
1. try to do _anything_ with obtest other than making it give the usage message
Actual Results:
segfault
Expected Results:
... No segfault..
