Ok so I've managed to get back into the system to try to correct my 
problem. I can boot it etc etc, but only by putting the info manually 
into grub as it's still dropping me into the grub> prompt.

I've done the usual n00b approach, unmerged grub and then re-emerged it, 
but this hasn't made any difference. Plus I'm also trying to re-run the 
genkernel too see what it comes up with.

Any further advice/suggestions please ???
