The init script on the initramfs failed at the same point - not a problem with the drivers, but a problem with what the scripts are looking for. I'd suggest looking at the scripts on the initramfs - its been my experience that they are the culprit and not the kernel itself. DRH -- Dialup is like pissing through a pipette.
