Because I had the same problem, never resolved, with the previous update
of the kernel (2.6.23.8 if I remember)

This is why I do not undertsand why ity does not work for me !

Like what ? I do not see any typo.
I already work around. I cannot see what is wrong. The kernel 
2.6.21-1.3194 is absolutely fine, but not the new ones. Same syntax.

Is it the password of grub ?

The first time that I installed a FC7 I had a problem with the 
root=LABEL=/ because I guess that I had 2 partitions on 2 different
drive with the same lable like /. So since that time, I avoid to use the
LABEL. When I will understand exactly what is going on, I will be able
to make more test. Right now, I have a kernel booting properly. Doing
the same thing and just booting another kernel should work and it does 
not.

Yes /dev/sda8 has a label /, as well as /dev/sdb5 which I only mount in 
read-only.

Yes
