Can't use firewire harddisk under YellowDog Linux!

[damm]

Hi. I have an iBook(G3 800). I bought a 1394 hard drive(the brand is buslink) and a maxtor 80G harddisk. I installed the harddisk into the hard drive and it worked fine under OSX10.2.8. But under YellowDog Linux 3, I couldn't use it. The 2.4.22 kernel even can't recognize that a device has logged in. The 2.6 test 11 kernel recognized it but can't use it. The following is the main output from 2.6 kernel when I probemod sbp2.(I checked all the necessary kernel options. Only sbp2 was compiled into a module, and the others were compiled into the kernel)
