Debian EeePC Live 1.0~b3 fails to boot with persistent storage

[Ariszló <ariszlo@gmail.com>]

I dd'd binary.img ( 2009-12-31) to my pendrive and then following the
instructions at
http://live.debian.net/manual/html/persistence.html
created a second partition labeled live-rw.

When I just hit enter at the boot screen then Debian EeePC Live boots
fine but if I add the boot parameter 'persistent' then I get this
error message:

This Debian Live image failed to boot.
[Snip]
Can not mount /dev/sda4 /live-rw-backing, fstype=vfat, options-rw

This is the partition table on my EEE PC 900:

/dev/sda1: SYSTEM
/dev/sda2: USER
/dev/sda3: BIOS
/dev/sda4: 8 MB EFI (FAT-12/16/32) partition
/dev/sdb1: HOME
/dev/sdc1: DEBIAN_LIVE
/dev/sdc2: live-rw
