A few manufacturers already offer Desktop Replacement class Notebooks using actual desktop processors.
For example, Alienware's
Aurora m7700 series can use any current 939-pin Desktop processor - that includes the entire Athlon 64 X2 dual-core series as well as the dual-core Athlon 64 FX-60
Furthermore, if you need more battery life, dual-core Turion processors are scheduled for introduction sometime this year (probably mid-2006).
