Oh, but the Adobe Color Printing Utility appears to use the new print path. I had to add it to Canon special casing file so I am pretty darn sure it does use the new printing path

The way "disabling" ColorSync works is exclusively through null transforms, meaning the PDF object source profile must be the same as the destination profile. If not, then a conversion will occur, even if in the GUI it appears you've correctly set objects to not color manage - and this in fact was a bug by default in InDesign CS3 were it used a different print path (PICT I think) and ColorSync double color managed everything. The solution was to check the Print as Bitmap option, which cased ID to rasterize the document itself, and submit it to Quartz PDF Context so it would be written out as (raster) PDF instead of PICT. Then the problem did not occur. Acrobat has had a similar problem intermittently as well.
