I wrote a small shell script <r.split.line> for splitting the raster map
into parts with the line(s). Hope it will be useful.

--------------------------------------------------
./r.split.line -help

Description:
 Split raster into parts with vector line(s). Lines MUST intersect the
whole raster map.

Keywords:
 raster,vector

Usage:
 r.split.line raster=name line=name [--verbose] [--quiet]

Flags:
 --v   Verbose module output
 --q   Quiet module output

Parameters:
  raster   Name of input raster map
    line   Name of vector map with line(s)
---------------------------------------------------

The script is attached.
