With only 1gig of RAM there is little reason for 64-bit addressing -- 1
gig is well within the range of 32-bit addressing (yes, you could set up
a large swap partition and have lots of virtual addressing, but
swapping like 8 gig of VM in and out of 1 gig of physical RAM would be
painful).
Also, 64-bit apps tend to be a little larger then their 32-bit versions
(fatter pointers, integers, etc.). With 1 gig memory will be a wee bit
tighter (modern 64-bit machines would normally have lots more RAM...).
With what is obvious and 'older' 64-bit system, being limited to 4gig
of RAM (which is still just within 32-bit address space), going 64-bit
with this system would not buy you much. If you want a consistent
operating environment, especially if you don't want to maintain two
separate sets of updates, keeping all of your boxes at 32-bit for the
time being probably makes sense. If and when you upgrade things, going
64-bit might make sense.
