title: remove uneccesary drivers during linux kernel build
body: <p>I was wondering if anyone knows a way to prevent building unneeded device drivers when building  the 2.6.32 kernel in Ubuntu 10.4 on VB?  The reason I ask is we have to do a project for my operating systems class that involves adding some system calls to the kernel and the instructions say that after you add your call you need to rebuild the kernel(which takes like 3 freakin hours) and I know its because Ubuntu doesn't know which device drivers I need on so it builds them all so I'm wondering if there is a way to have it only build the ones I need? and if so how to go about that? or if anyone knows a way of being able to test added system calls without rebuilding the whole kernel(as this is really the issue)?</p>
  
  <p>Thanks in advance</p>
