Yes, you can install Ubuntu 32bit on a 64bit system, and contrary to popular belief, it will be able to use all of your memory (not just 4GB). Just install it using the Linux PAE kernel (installed by default) and everything will run exactly the same. PAE stands for Physical Address Extension, and it is the technology that allows the software to access over 4GB of RAM.

Yes it will work but your system won't be in full use. So you may find that it won't be able to use as much RAM as your laptop has and the processor ability. Basically it won't perform as well as 64bit would.

I think more the question is here is how to install the ia32-libs? What errors are you getting?

Many programs will use more RAM when running as 64 bit, so depending on circumstance, you might find performance is actually worse on 64 bit. – Jonathan Hartley Jan 8 at 3:58
