Although I do not think they will care very much, but it falls within their area of responsability; Debian cannot fix non-free software. Have you tried to reproduce this issue using the free nVidia drivers? You might have some less capabilities (i.e. the ability to drive the four screens) or speed, but it should help you determine whether it's something caused by Debian or by their non-free drivers.
