The card ID in the code is 4220 and yours has is 4222. Edit
/sys/dev/iwi/if_iwi.c and add:
        { 0x8086, 0x4222, "Intel(R) PRO/Wireless 2200BG" },
 after line 123.

If you are loading the module, you can just rebuild that. Otherwise
you will need to rebuild the kernel. If you are not familiar with
building a module, rebuilding the whole thing, kernel and modules, is
probably the best idea.

Note that I don't currently have any 2200BG card, so I have not done
any testing. I looked at the pci.ids file and it does not seem to have
an entry for 0x4220, but does have one for 0x4222, so I am a bit
confused, but the pci.ids file is not relevant to the driver. It's
just an oddity.
