Matt,

What platform are you working on?

I really don't know why things are screwed up.  I don't remember fixing
a bug about band packing in MapServer.  I doubt the issue would be in GDAL
though 1.1.9 is pretty antique.  If you can bundle up the mapfile and
dataset(s) to reproduce the problem I could try it here and see if it works
fine on my configuration.

In general, I would encourage upgrading to GDAL 1.2.0 and MapServer 4.2 when
you get a chance, but I am not convinced yet it will solve your problem.

Best regards,
