I've created the USB key like this (more or less) and did not specified
or changed anything in the boot-sequence:

# dd if=/dev/zero of=/dev/da0 bs=1m
# fdisk -BI /dev/da0
# bsdlabel -wB /dev/da0s1
# export EDITOR=/mnt2/usr/bin/vi
# bsdlabel -e /dev/da0s1
# newfs -m 0 -o space /dev/da0s1a
# mount /dev/da0s1a /mnt
# export DESTDIR=/mnt
# cd /a/cdrom/7.0-RELEASE
# for i in base manpages catpages
  do
    cd $i; echo y|./install.sh; cd ..;
  done
# rmdir /mnt/boot/kernel
# cd /a/cdrom/7.0-RELEASE kernels;
# cat generic.??|tar --unlink -xpzf - -C /mnt/boot
# cd /mnt/boot && mv GENERIC kernel
# echo "/dev/da0s1a  /  ufs  rw,noatime  1  1" >/mnt/etc/fstab

# cat <<EOFRCCONF >/mnt/etc/rc.conf.local
#!/bin/sh
tmpmfs="YES"
tmpsize="128m"
varmfs="YES"
varsize="128m"
populate_var="YES"
hostname="eeePC"
keyrate="fast"
keymap="german.iso"
EOFRCCONF
# chmod 0755 /mnt/etc/rc.conf.local
# chroot /mnt /usr/bin/passwd root

and again: the USB key works fine in the eeePC 900 and other laptops I
have;

here is what is in /mnt/boot:
