Could it be related to KMS? I really don't have much experience with KMS but from reading messages on this list I got the feeling it's something that can affect (i.e. possibly screw up) both the console and X together, which sounds like your problem. You might want to look at http://wiki.debian.org/KernelModesetting and try the advice under the section "Disabling KMS"... -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
