Well I seem to have completed things as far as I can i.e. I've managed 
to get into it all the way as far as completing the kernel upgrade - a 
small anomally seems to have been that this time the "genkernel" compile 
(I use the flags/arguements or whatever you'd call them so that normally 
it modifies the grub.conf as well) produced an empty grub.conf, but 
there was also a file called grub.conf~ I'm not sure where or why the ~ 
appeared but I renamed/overwrote the grub.conf file with it - that 
appears to be OK.

The only issue remaining is that when I reboot the system, I still end 
up at the grub> prompt rather than grub firing up and offering the 
various (well, the only) version(s) for me too boot.

Thats stumped the hell out of me - I've been trying to get my head round 
the grub manual, the grub faq's, etc etc and not making any progress - 
I'm guessing that theres something that it just isn't finding, but I've 
got no way of confirming that.

Hence any ideas or suggestions are still (as ever) greatly appreciated - 
I still don't follow why this has happened, because I've upgraded the 
kernel about 3 or 4 times since I re-installed the gentoo without any 
problems???
