To what end? Why would you install a 32-bit OS on 64-bit hardware?
Jim, people (and myself) have pointed that out earlier in this thread:
running 32bit apps running 32bit virtual guests.
Both use less memory in 32bit.
The reminds me the argument that we shouldn't switch to IPv6 because routing tables would need more memory which would make routers more expensive. Memory prices (in e.g. dollars per MB) have dropped by several orders since the argument started to appear back in the 90's but the mantra keeps being repeated until today and will be repeated on and on. It's the same here: my first 64-bit machine built in 2003 or 2004 had 2GB of RAM (perhaps even 1GB, I'm not sure); my strongest machine today (built in the end of 2012) has 32GB - and I might have actually paid less for these 32 GB than for those 2GB back in 2003 (certainly not much more). That's factor of 16 and I hope even you will agree that's much more than the ratio between x86_64 and i586 memory consumption. At one moment, you simply need to bite the bullet and switch. Otherwise, you will keep repeating the "bigger memory consumption" mantra even if, from the long term perspective, it gets more and more ridiculous. The reward of getting rid of all the low/high mem trickery, vmalloc area limited to ~130 MB, limited register and instruction set or inefficient parameter passing (and I surely forgot a lot more) is worth it.
