Correct me if I'm wrong, but it is intended to fit into a standard
(socket 939) motherboard¹? So if there is a demand for quiet PCs (in
addition to laptops), the market should be ready.

IIRC, Turion fits into a standard s754 board (must have BIOS and
voltages to support it). May be also a good upgrade path for 754
board owners, though on expensive side (naturally, mobile parts were
always more expensive than their desktop brethren).

¹ Of course, it'll be one of those with a big heatsink and fan on the
chipset, and a separate PSU for the two graphics cards :-) |

Turion64 comes in (peak) 25W and 35W, I would think idling on 50% of
max is rather high? BTW, are low-voltage dual core parts even
available?

Right - I just found a web store selling them.

The price is not too bad, actually. Certainly cheaper than
Pentium M, both motherboard and chip.

Supposedly AMD uses a process tweaked somewhat differently for its
mobile parts, so the two may not be directly comparable.
BTW, are low-voltage dual core parts even
Beats me - though IIRC they haven't been out as long as the single-core
parts were before LV versions appeared there (then again, having
followed that road already it shouldn't take as long to retrace it).

Both Windows and Linux support tying a thread or process to a given CPU;
it's hard to imagine a SMP-capable OS that doesn't. Linux has some support
for efficient memory allocation on NUMA systems, although it's a good deal
more limited than what you suggest.
