As far as I understand it, the vbi device is needed to read |
| 34 |
the channel names from teletext. I suppose the scanning |
| 35 |
would work perfectly if only the vbi access could be |
| 36 |
skipped. |

This seems to be a Gentoo specific problem as the scan |
| 39 |
used to work on my old Debian. As I mentioned AleVT works, |
| 40 |
too. |
