We run 64bit on most machines cuz they've got more than 4 gig ram.
(And any besserwissers about to sound of about PAE kernels can kindly
do so in another thread cuz I'm NOT listening!)

As an aside, I hadn't heard of issues with 32bit xfs but in retrospect
it can see the logic in it: a lot of company-supplied code has had
64bit issues cuz it came from a 32bit environment, but SGI was never
"most companies" :-)
