I don't think it was really meant to support both SCC and SMC at the same time. I ended up splitting the driver into two different drivers, making one work just for the SCC, and the other only for the SMC. This works quite well. The code is in the QSLinux release, which you can download from ftp:://qslinux.org. When you untar the kernel you can find the two drivers in the directory snmc/qslinux/kernel/drivers/char.
