That's easy - just use an averaged normal_map

e.g.

#declare bump_mapping =
 normal {
  bump_map {
   png "wood-bump.png"
   interpolate 3
   bump_size 10
  }
  rotate x*90
  scale 100
 }

#declare micro_normals =
  normal {
   bumps 0.5
   scale 0.001
  }

plane {
 <0.0, 1.0, 0.0>, 0.0
 texture {
  pigment { rgb 0.3 }
  finish { reflection 0.8 conserve_energy }
  normal {
   average
   normal_map {
    [ 1 bump_mapping ]
    [ 1 micro_normals translate <rand(s), rand(s), rand(s)>*1000 ]
   }
  }
 }
}

Cheers,
Edouard.
