It's not a bug, but a feature. Look into your kernel configuration file,
specificaly at the line for sio2. You'll see it has the word "disable" in it. Just
remove it and make a new kernel. In 2.1.0 the probe for sio2 and sio3 was on be
default, which caused some problems with some video cards. For this reason, in
2.1.5R the GENERIC kernel does not probe sio2 and sio3 by default. However, it is
easy to change that by just removing that "disable" keyword from the configuration
