The instructions for the 300D are very explicit about the Adobe RGB
setting, "This is used mainly for commercial printing. Since the image
will look very subdued, image processing will be required. This setting
is not recommended for users who do not know about image processing and
Adobe RGB." Obviously they have had lots of complaints about "gray and
dismal". Now I know you know lots about image processing and Adobe, but
here it sounds like you are trying to get good results right out of the
camera.

The Adobe color space is really quite different than sRGB. Please excuse
the sample camera, but it wasn't in the review of the E-1
<http://www.dpreview.com/reviews/canoneos300d/page11.asp>. See the
bottom of the page. There is no change in the yellow/red border, but
more range from green right around to red, going well beyond the sample
subject.

Have you tried changing the color temp for Adobe? In PS CS RAW
conversion, one may simply move a slider and watch what happens "live".
Maybe WB that's right for sRGB isn't right for Adobe RGB?
I shoot RAW and convert to Adobe. The result is usually pretty flat,
sort of like Portra NC on a flat day. Local contrast enhancement and a
bit of curves generally brings things up.

Have you tried a custom WB setting? Or fine tuning the preset WB
settings? Dpreview said of the E-1 that it's WB Kelvin settings didn't
agree with their their measured studio lights:
"White Balance Fine Tuning
You can also fine tune each of the preset white balance settings by a
value of -7 (warmer; red) to +7 (cooler; blue). As you can see from the
samples below the preset 3000 K was best tuned to '-7' for our studio
lamps (which is a bit odd because they have a measured WB of 3000 K)."
You can see their samples (and download larger images) here

As above, it's quite different. I've also wondered how that plays into
response curves. Maybe the mappings have inherently different curves.

Just becasue they say CM4 is for portrait doesn't mean it's right for
your portraits. Have you tried CM2 and 3?
Just for a lark, I might try lowering contrast and raising sharpness and
saturation in different combos. I can't even explain my rational. In
fact, I'd probably sit down with any RAW converter that allows live
preview and play with the parameter sliders a lot. Whatever workd best
can then be made a custom setting in the camera.

How about putting a very slight warming filter on the lens, making a
custom WB, then removing the filter? That should fool the camera into
sightly stronger cooling, and might take the red down just that little bit.
