Hi Aleksey,
Yes, I think this is the same problem. This fix requires changing two
files, one in the initrd.gz, one in the main filesystem. Fortunately you
can make this second change in the casper-rw filesystem, so there's no
need to rebuild filesystem.squashfs ..
The first _is_ a bit of a pain because it means unpacking and repacking
the initrd. The quick and dirty way to do that (i.e., as root), is to
copy the initrd.gz to /tmp and do something like (untested):
cd /tmp
gunzip initrd.gz
mkdir ird
cd ird
cpio -i <../initrd

And then overwrite the initrd.gz on your live USB/CD with the generated
'newird.gz'.
The second file is easier, boot the live CD/USB with persistence enabled
and then (as root) do:

I've not yet tested this fix with jaunty, but it seemed to work for me
with intrepid.
