Why? I don't really know, the kernel is not finding the partition with
the label "/". You could try replacing the root= parameter with the real
device of the "/" partition. As in:

>         kernel /vmlinuz-2.4.20-4.ll.acpi ro root=/dev/hdax hdc=ide-scsi 
> acpi=off

Where the x in hdax corresponds to the root partition. You can seen the
partitions of hda by typing:
  /sbin/fdisk -l /dev/hda

Yes, except that I have not provided a newer version alsa kernel modules
package for 2.4.19-1.ll
