I assume what you have is contour and possibly breakline information?  Or
is it point elevations?  Building a decent raster DEM from contours and
breakline information is not a trivial process.  I worked on some algorithms
for it at PCI but I am not aware of anything directly available built on GDAL.
You could use commercial software, like PCI.  I also think there may be a
decent contour to raster program in GRASS but I am not sure.

If you just have point data, any point interpolator would likely do, such as
the one in OpenEV mentioned by Tyler.

MapServer is good for a variety of rasterization issues, but it isn't an
