Did you copy to the ramdisk, then edited the kismet.conf and kismet_ui.conf files to contain the correct capture source, then start kismet with -f pointing to the edited conf files ?
No I don`t know how to do this.
Do a "man kismet.conf" & "man kismet_ui.conf" for more information.
I think I need to do more reading as at the moment I`m unsure what it all means.
Do a "dmesg | less" to see which drivers are loaded for the card.
I`m guessing on this one I get init_module

rism2_pci.0: 0.2.0 loaded
init_module:dev_info is

rism2 pci no devices found, driver not installed are what I`m looking for?
