This may have to do with some of the customizations Red Hat makes
regarding their boot shell - nash. I have never been able to figure out
exactly where the ability to read labels at boot time comes from. I
would suggest you try using the actual device name your root partition
is on in your grub.conf entry for this kernel rather than a label and
see if that works.

For example:

title Red Hat Linux (2.4.28smp)
        root (hd0,2)
        kernel /vmlinuz-2.4.28smp ro root=/dev/hda hdc=ide-scsi apic
        initrd /initrd-2.4.28smp.img
