I also own a 4490 Photo.
I was running Gentoo 64bit on my workstation some times ago, but the
epkowa backend was not provided for 64bit arch (this is not the case
anymore, but I'm lazy, so I didn't change my config). The way I've
found to use the scanner with Gentoo 64 was connecting the 4490 to a 32
bit Gentoo server running saned+epkowa, and access it through the net
64 bit reinstall is planned for next September.
