Just to clarify a few things...
I was finding that I got unexpected results while printing using Canon papers
from the Adobe RGB color space (from Photoshop CS). Things were better when I
selected ICM when printing, and digging through the documentation, this causes a
conversion to the sRGB color space before printing. Canon did send me info
about how to print from Adobe RGB while retaining max. gamut, but it turns out
that info did not apply to the i9000 printer.
Again, I'm still trying to get clarification from Canon on all this; so far the
common theme among the replies is that it's best to use sRGB with this printer.
As someone else said, this seems unbelievable, if true. In fact, here's a quote
from a Canon tech: "At this point only the i560, i860, i900D and i960
driver contain the Adobe RGB profiles."
This seems like unbelievable sloth on Canon's part so far... How can they
expect to compete with the Epson 1280 with this kind of support? Can you tell
I'm mad?
Adobe RGB isn't a printer color space. It's suitable
only as a working space or profile connection space
(PCS.) Unless you have a suitable ICC profile
(.icc or .icm) for your printer, you will need to let the
printer driver do your printing for you, and use sRGB
as your working space.
A few paper and ink manufacturers have generic
profiles available for download (eg. Red River Paper).
You can also find a few here:

In a nutshell, it's not really Canon's responsibility
to provide profiles for every available paper that
you might choose to print on. As is typical, they've
chosen to provide a handful of proprietary profiles
for their own papers, assuming you use their own
ink as well. These should work fine, as long as
you stick with sRGB as your working space.
With a proper ICC profile for the printer/paper/ink,
you should be able to use whatever working space
you like, as long as you follow the proper procedures
for the image editor you're using -- either Photoshop
or some other ICC-compliant tool.
