Well subject says that all, but some details.

When I try to modprobe the sb module, which worked for me in 115 it sais
sb_card: I/O port 220 already in use, but thats not true because before I
try to insmod them I did the cat /proc/ioports and it went ok.

here is a first few lines from /proc/ksyms if it helps:
