[Bdi4emc-help] Writing a stepper driver and have a couple questions

Hi All, I'm writing a new stepper driver on BDI 4.38, so I can run my x10 microstepping Gecko drives on the P266 laptop that I have allocated to the purpose. The effort has taught me what a pain it is to get a patched kernel and EMC running from available source and information. Now that I've figured out that I don't have to patch the kernel or adeos, I can use BDI, and in thanks for all the hard work that must have gone into it, I'm willing to release the driver under GPL when it's done. Are you guys still accepting code submissions for the BDI branch of EMC? If so, what's the best way to go about that? Also a little technical question: freqmod has an empty function called freqsig(). What's that for? Thanks, Matt
