I noticed this on the Epson UK site today:
http://www.epson.co.uk/Printers-and-...EGORY_CODE=DRV :
new driver at 28/5/09, of which is said: "The Advanced B&W mode (if available as driver option) and Color mode is improved with the driver option "No Color Management" and Adobe Photoshop CS4". May be of relevance to your question.
