This sounds like you haven't configured X to use the correct framebuffer.
You may have more than one framebuffer device - if you're using a distro
kernel then the motherboard's on board graphics (if it has one) or your
"normal" video card's might be loaded first and gets /dev/fb0.  If 
ivtv-fb is being loaded after this it will get /dev/fb1.

Your XF86COnfig-4 file should have something like this in it.
    Section "Device"
        Identifier  "Hauppauge PVR 350 iTVC15 Framebuffer"
        Driver      "fbdev"
        Option      "fbdev" "/dev/fb1"
        BusID "0:0x0b:0"
    EndSection

The device that ivtv-fb is using is reported at the end of the driver
being loaded.  Have a look at dmesg to find which framebuffer device
ivtv-fb is using and make sure that the one configured in XF86Config-4
matches.  

Hope this helps
