not sure about atv_bootloader, and kexec.
/dev/sdb sounds about right for dev name,
but can also be sda or sdc. looking at the tutorial
I see a sdg:
# Verify that it looks fine and the atvrecv flag is set
sudo parted -s /dev/sdg unit s print
Model: CBM Flash Disk (scsi)
Disk /dev/sdb: 2015744s
Sector size (logical/physical): 512B/512B
Partition Table: gpt
(not sure why, maybe sdram or something);
here is a thread for grub:
http://ubuntuforums.org/showthread.php?t=224351
using grub2 I usually use grub-setup
to create stage1(if I remember correctly)
the location for all of these files is:
/boot/grub
there you have all of the grub modules etc...
but you also need to make sure the device(apple T.V.) knows where to
find /boot/grub i.g. root (hd?,?); on the macbook
when starting after the "GOOOONG" and pressing "option"
if you have that correct you should see a disk, but if incorrect
you will see nothing.

As for:
dd if=tmp/mbr_fast-1.0.bin of=/dev/sdb bs=512 count=1
this is confusing to me:
if=tmp/mbr_fast-1.0.bin
do you see anything in /tmp or wherever this might be located.
