I guess your system in jinxed because of the hostname you setup :-p

Ok, more seriously now. This is the nvram data I mentioned earlier. This 
system may have that info stored in efi variable. You should be able to 
find it in /sys/firmware/efi/efivars/nvram-*.

It may be necessary to run the following commands:

# modprobe efivarfs
# mount -t efivarfs efivarfs /sys/firmware/efi/efivars
