One thing to watch out for, you need to leave enough sectors before
the first partition so that grub can install its first stage loader.
The second stages go in /boot/grub
I think this is 32 or 64 sectors. fdisk will probably do that for you,
but when putting grub on flash disks, sometimes special care needs to
be taken to get grub to fit.
One thing I do now is leave 1000MB ext2 for /boot, but that is just
me, as I am a kernel developer and need to have multiple different
kernel versions ready to boot.
If it interests you, a default install of Ubuntu leaves 200MB ext2 for /boot.
