Ken,

It looks like Lichun Wang (ITC) did a significant overhaul of the
header writing for ENVI format very shortly after 1.2.6 release.   Are
you using 1.2.6 or GDAL CVS?  I would encourage you to try a
nightly snapshot if you are currently using 1.2.6.

Looking at the code, it seems it should always write out the
geotransform information as a mapinfo line, even if the coordinate
system is not known.  What does the generated header file look like?

Best regards,
