well, I didn't see any issues, but I used it in a homogeneous 96x cluster:

default nfsroot
#default flash
#default fromdisk

label nfsroot
        kernel /vmlinuz-2.6.11.11-x
        append root=/dev/ram initrd=image.gz init=/linuxrc vga=ext panic=60
        ipappend 1

label flash
        kernel /memdisk 
        append initrd=/dl145-2004.10.08.img

label fromdisk
        kernel /test
        append root=/dev/hda2 vga=ext
        ipappend 1

regards, mark.
