I can change the countrycode to other (valid) settings, but I have a feeling that setting that at runtime is already too late. > there is a way again on some cards to tweak the card's eprom memory > to get the > extended channels It was my impression based on the research I did before purchasing the card that there aren't multiple SKUs representing hardware for different regions -- just the one card which can cover the full range of frequencies.

The hardware is built into a weathertight box mounted on the outside of a structure; there's no console. The system boots via PXE and mounts its root filesystem via NFS, though, and I have remote power control as well, so I have fairly complete control over bootup. Is single-user strictly necessary? ++J
