Hi, its me again (c: First of all, is it supposed to be working with 2.2.19 or should I take a new 2.4.4-ac kernel for that support ?

I was doing i2o_install_controler, and after that i was trying to do a i2o_pci_enable or i2o_pci_bind,because they are the only fonction that seem to bind i2o with a pci_dev, but I get unresolved error with those functions ... if I do a cat /proc/ksyms I dont see them listed there. After that when I do i2o_delete_control, I receive a segmentation fault !!! (Those test are done in 2.2.19) I have built my kernel with i2o support and i2o_pci support !!! As for the spec, I have the i2o spec 2.0 here. Is it supported ?
