All:
I have a large group that uses the ssb module along with the Broadcom 
4318, in a CF form factor. If the CF card is inserted before boot, and 
the ssb module is not in the initrd process, the laptops lock up and do 
not become operational. The solution to this problem is/was adding the 
ssb.ko to the initrd process. So I agree with Luis on this, the ssb 
module will have to be added/updated to the initrd process. As for PCI 
operations, I don't know, but for PCMCIA operations ssb.ko has to be 
added and/or updated. Anytime I am testing new releases of b43, I run 
"update-initramfs -u" to update the ssb module. (Sometimes you can do a 
rmmod ssb and rmmod b43, and then modprobe them back in. - This saves a 
reboot)

Thanks
