The problem is what size do you make the image, not all USB sticks are
equal. A simpler option is to use Unetbootin to convert the ISO onto a
USB stick.

Incidentally, you could try dd'ing the ISO to a USB stick, this works
more often that you might imagine.

While I'd also like to see USB boot media, I'd like to observe that
SystemRescueCD, which is based on Gentoo, is perfectly good to use as
an install medium.

here's one I prepared earlier

This is from 2008:

and these are some notes of mine on syslinux which may help a bit too:

waltdnes@i3 ~ $ emerge -pv unetbootin

I have done that. Here's basically what I did.

#!/bin/sh

ISO=/home/ftp/pub/install/install-amd64-minimal-20081213.iso

mkdosfs -F 32 /dev/sdc1
dd if=/usr/share/syslinux/mbr.bin of=/dev/sdc || exit
mount -o loop,ro -t iso9660 $ISO /mnt/iso || exit
mount -t vfat /dev/sdc1 /mnt/media1 || exit
cp -r /mnt/iso/* /mnt/media1 || exit
sync
mv /mnt/media1/isolinux/* /mnt/media1
mv /mnt/media1/isolinux.cfg /mnt/media1/syslinux.cfg
rm -rf /mnt/media1/isolinux*
mv /mnt/media1/memtest86 /mnt/media1/memtest

umount /mnt/iso
#vim /mnt/media1/syslinux.cfg
sed -i -e "s:cdroot:cdroot slowusb:"
-e "s:kernel memtest86:kernel memtest:" /mnt/media1/syslinux.cfg

umount /mnt/media1
syslinux /dev/sdc1

try the manual from the systemrescuecd (a very recent gentoo based livecd)
