I bought my X60s with 500 MG of RAM, upgraded to 2.5, which was not
recognized till I installed a PAE enabled kernel for my 32 bit Kubuntu.

Now I upgraded again to 4 GB RAM, but even with PAE enabled only 3 are

Would it help to upgrade to a 64 bit version of Ubuntu?

On my X200s the 4 GB RAM are recognized via PAE, so I presume the answer
would be no, but I don't really understand the differences between PAE
and 64 in all details.
