I'm using the header that comes with OGR. Don't know if there is a
possibility to change the header via OGR (but my dxf knowledge is very
limited, so I'd prefer to go with the default).

Setting a style string in mm (e.g. 'PEN(c:#0000ff,w:5mm'), the dxf

100 (most likely because in dxf, one width unit is 1/100 mm). This seems
strange to me, shouldn't the driver treat mm as paper units (instead as
ground units) and just multiply the mm by 100?
Didn't look at any code - but the units in DXF are configurable. So the driver
should do that only if it knowns the current units. It might assume running
with the DXF header shipped with GDAL (assuming there is one) and you are using
another one?
