Probably just because not many people have access to that kind of
hardware. Have you tried building on Linux on Power?

Also, I believe Opterons can do up to 4 DIMMs per memory controller, so
with 2G sticks an 8 way Opteron could hit 64GB, which isn't exactly
shabby, and I suspect it'd cost quite a bit less than a comperable
p570...
