First of all, just in case you no longer have the patch, I've attached it to 
this message (as pm-init-2.patch).

I believe you've built brltty for yourself. If you still have the source tree, 
then use it. If you don't, check it back out from the repository. If you're 
using an already configured tree, there'll be no need to reconfigure it.

To apply the patch, do this:

   cd /path/to/brltty
   patch -p0 </path/to/pm-init-2.patch
   make

That's all there's to it. Change to the top-level directory of the tree, apply 
the patch, and then just make and install. After that, restart brltty so that 
the version with the patch is running. Then, do whatever you normally do and 
see if it still fails or if it works. If you can, please keep a log file so 
that, in case it still doesn't work, we can have another look.

You can remove the patch in one of two ways. One is to use svn's revert 
function. The other is to add the patch command's -R (uppercase) option, like 
this:

   patch -p0 -R </path/to/pm-init-2.patch
