excessive /boot entries

[Lisi Reisz]

This being someone else's computer I don't want to "suck it and see", which is 
probably what I would do on one of my own computers.

So:  Last time I had this computer to work on (about a fortnight ago) I edited 
the overlong menu.lst to reduce the very large number of kernel options to a 
manageable number.

Now, two weeks later, the list is again enormously long.  

On investigation I found that there are about 60 kernels in /boot(1), from 
which I imagine that menu.lst has retrieved its very long list.  Can I safely 
remove most of the entries in /boot (rm foo), and then edit menu.lst, and if 
so, which do I need to keep.  Not only are there more kernels than seem 
necessary (or desirable!), but each seems to have too many options.

So:  Which entries should I keep?

TIA
