Mehall: If you want to send me a copy of dsdt.dat, I will try to use Scott Minster's diff file to see if I can get your DSDT in a manageable state. You can send it to me by email through the Ubuntu forums. If you do get in a non booting state, you can use a live CD to delete the DSDT.aml file from /etc/initramfs-tools. It will not find it and default to the original DSDT to boot. You can then run "sudo update-initramfs -u -k kernel-version" in a terminal to remove the link to the custom DSDT file to start over.
