The LSB also says all packages must specify an architecture of x86_64
and is distributed under the GFDL.  I don't readily see where it
references /lib64 except for the loader and to say that libraries should
be in a directory.

What the users *want* is a useful 64bit system sometime within the next
millenium.  Then there's the issue that 64bit on amd64 is *faster*, as
well as able to address a decent amount of memory.  Speeding up certain
programs shouldn't be (and isn't) what we're interested in.  Providing a
distribution that takes advantage of the capabilities of the
architecture is much more what we're shooting for.

I hardly see them as exotic, I've got 3 dual-proc ones that I've been
trying to get something useful on.  Most people will also be running
Windows on their 64bit machine.
