Except that many people run a 32-bit OS on their AMD64s so it really
depends on what kernel he's running.

uname -a

and looking for the processor type would be a better indication:

mark@lightning ~ $ uname -a
Linux lightning 2.6.15-rt2 #2 PREEMPT Thu Jan 5 16:13:25 PST 2006
x86_64 AMD Athlon(tm) 64 Processor 3000+ AuthenticAMD GNU/Linux
mark@lightning ~ $

So this is a 64-bit kernel running on a 64-bit processor. However I
have a chroot'ed 32-bit environment on the same machine:

lightning ~ # uname -a
Linux lightning 2.6.15-rt2 #2 PREEMPT Thu Jan 5 16:13:25 PST 2006 i686
AMD Athlon(tm) 64 Processor 3000+ AuthenticAMD GNU/Linux
lightning ~ #

The 32-bit area runs Java, Flash, win32codecs, etc., successfully. The
64-bit does not.

CREDITS: Many thinks to Billy Holmes and others on the gentoo-AMD64
list for helping me with this.

Cheers,
Mark
