   sadly, that didn't work as well as it might have:

"Kernel panic - not syncing: VFS: Unable to mount root fs on  
unknown-block(0,0)"

that suggests the initrd image was not built properly?  and,  
annoyingly, there is no timeout that allows me to select the original  
kernel to boot.  time for a live CD and some repair, i guess.  not  
like i haven't been down *this* road before.
