Unless you have a complete schematic, I would not end think about it.
The conversion circuit is highly tuned...and if done properly will take into account the characteristics of the FET.
You would get more improvement by upgrading the capacitors. Same value, same voltage, lower ESR.
What! I love the part about the iPhone.
I would say, people have but it would be to overclock older systems. Modern motherboards have very well designed DC-DC power converter systems. Today's VRMs are a high degree better than some generations ago. Now that we have I2C and SMBus controllers, the CPU and VRM can communicate in a faster and more controlled environment. The faster ADCs that are used today enable VRMs to sample feedback signals faster, and tune the PWMs to be as clean as possible. Furthermore, the materials used for today's inductors and capacitors cause little impedance and lower power dissipation. This in turn allows the system to have clean signals in the first place.
Also, you don't need a schematic.
I can find IR parts pretty easily among others (see my mobo reviews). Just takes looking at the numbers on it and googling.The information for these parts cannot be found online due to NDA/buisness agreements, and the like.
