This is good, then.

I would expect the following entries should run your system, if not,
probably there is a problem with the kernel options.
### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'GNU/Linux, with Linux 3.2.6-lfs-7.1' --class gnu-linux --class gnu
--class os {
load_video
insmod gzio
insmod part_msdos
insmod ext2
set root='(hd1,msdos1)'
search --no-floppy --fs-uuid --set=root 63a59ea4-b2dd-4ede-a506-14b8d0a951c5
echo 'Loading Linux 3.2.6-lfs-7.1 ...'
linux /boot/vmlinuz-3.2.6-lfs-7.1 root=/dev/sda1 ro
}
menuentry 'GNU/Linux, with Linux 3.2.6-lfs-7.1 (recovery mode)' --class
gnu-linux --class gnu --class os {
load_video
insmod gzio
insmod part_msdos
insmod ext2
set root='(hd1,msdos1)'
search --no-floppy --fs-uuid --set=root 63a59ea4-b2dd-4ede-a506-14b8d0a951c5
echo 'Loading Linux 3.2.6-lfs-7.1 ...'
linux /boot/vmlinuz-3.2.6-lfs-7.1 root=/dev/sdb1 ro single
}

Ken has replied. After you try his suggestions, if successful, please,
skip the rest of this message. I will try to coordinate my reply to
include some observations about what I read in Ken's reply. I am trying
to help too, because I have LFS in VMware Player.

As Ken wrote, no need for initrd.
Some of the things I will write below are different from the book, but I
think they are worth a try.
For the grub.cfg menu, after chrooting into LFS, you can save the LFS
grub menu with a different filename, as Ken suggested, and generate a
new one automatically with the command
grub-mkconfig -o /boot/grub/grub.cfg
As said before, this will overwrite /boot/grub/grub.cfg!!!
The generated menu would have menu entries similar to the ones I gave
above, but with "/etc/grub.d/10_linux", instead of
"/etc/grub.d/30_os-prober".
For the kernel scsi options, I have the following (obtained by trial and
error, so some might be irrelevant). I removed commented (not set) lines.
# SCSI device support
...
# grep -i scsi /boot/config-3.3.6 > /home/fernando/tmp/grep-config-3.3.6.log
# sed -i '/^#/d' /home/fernando/tmp/grep-config-3.3.6.log
