   This is true.  It strikes me that there are options here.   
      
   Virtualization with emulated devices is the obvious one.   
   While it doesn't eliminate it, this at least limits the scope   
   for drivers one must implement, if one is willing to use, say,   
   virtio for things like block storage, networking, etc.   
      
   Another option would be to use something like a rump kernel to   
   provide drivers for actual devices.   
      
   Porting drivers from existing systems is always an option,   
   though one that is a fair bit more labor intensive than the   
   others.  Still, for a particularly complex device, it may be   
   less overall effort than building a new driver from scratch.   
      
   In many ways, we are lucky these days: there's far less   
   variation across bus architectures, storage options, etc, as   
   there once was.
