I just did this last weekend.  Here are my ivtv packages from atrpms:
[root at myth ~]# rpm -qa | grep ivtv

Atrpms doesn't have the ivtv xdriver so I compiled the ivtv xdriver myself
grabbing the trunk tarball from

Then /etc/rc.modules contains:
modprobe ivtv
modprobe ivtv-fb

And /etc/modprobe.conf contains:
alias char-major-81 videodev
alias char-major-81-0 ivtv 
install ivtv /sbin/modprobe --ignore-install ivtv; /sbin/modprobe ivtv-fb 

*uncheck* "use PVR350" output in mythfrontend's display configs.  Using the
mpeg decoder on the PVR350 is broken with 2.6.22 right now.  However, X11 with
Xv over the ivtv framebuffer is fine.

And here are the relavent sections of xorg.conf:
Section "Monitor"
    Identifier "Sony TV"
    HorizSync 30-60
    VertRefresh 50-100

        Flags "-HSync" "-VSync"

    # calc from resolution (int(x*0.254)  int(y*0.254))
