The  dmidecode  utility is cool to learn about.  But, when I run it
on my laptop, it says:

Physical Memory Array
        Maximum Capacity: 2 GB

I am currently running with 3 GB.  I know the machine won't take
4 GB.  The reported number is the "official" number for a Thinkpad
T60, which is often lower than what actually works.

On the other hand, aren't there are memory limits for 32 bit linux?
Or at least some magic needed for grub.conf?  Any issues with suspend,
when the RAM gets large?
