Hum, let's see. I think the alpha port works since 95, the sparc 64
has been around since 96 too, and as far as I can tell we also reliably use
the following 64 bits architectures:
- Intel Itanium
- AMD Opteron
- PPC 64bits
- S390 mainframe 64 bit mode
So I count at least 6 supported 64 bits CPU. I think there is also
Mips 64bits but I never had a chance to play with it myself, linux support
is available for them too I think.
The main problem is more general availability and price of those
platform (though the AMD opteron boxes available around seems okay).
So I really wonder what made you think Linux ain't really there. Actually
Linux tends to be the first OS ported to new (64 bits) chips those days.
