Hm, I don't really know genkernel. Does it create the initramfs? |

Then there's either no daemon that creates the devices (udev) or it |
| 15 |
isn't somehow configured correctly. |

Somehow I doubt that. Usually you have it either the one way or the |
| 21 |
other. But as you said you could load them, I guess they're modules. |
| 22 |
You might want to try to recompile a kernel with all drivers compiled |
| 23 |
in. |

That would explain it. udev would be needed in the initramfs to create |
| 31 |
devices upon module loading. |

So there's no hotplugging or similar. Try to compile the drivers |
| 36 |
directly into the kernel. |

Ah, this _is_ in the initramfs? Is there a udevd spawned in initramfs? |

Is "dmesg" available in initramfs? It may contain hints upon module |
| 50 |
loading. But at that time those hints should be print out to console, |
| 51 |
anyway. You're shure that those are the correct drivers, aren't you? |
