Well, the hardware in question would be IBM server hardware with 16
gigabytes of memory.
x86_64 is still a new technology and EM64T processors are not readily
available. And your x86_64 support is scheduled for April in any

But yeah, I understand that it might not be worth the effort if it is
no small tweak. Just exploring all the options here.
