Oh wow, awesome! He's on a 32bit machine, but I can try my hand at rebuilding the kernel with your patch! How exciting!

Unfortunately, something changed in the kernel between 2.6.32 and 2.6.38, and now the speakup_dectlk module produces the following cryptic error on boot:

Kirk informed me that there was a change in how serial ports are allocated, and that there is a one-line fix that can be made in the probing code. I'm more than willing to do this, but I lack the knowledge to locate the fix, additionally I don't know how to recompile just a single kernel module, and recompiling the whole kernel seems overkill. Additionally, this fix should be pushed to the kernel source, so all may benefit.
