[mythtv-users] Mythtv + DXR3 ?

Hi,
I also have a DXR3 which I already have installed. I am running gentoo linux and I used this:
ACCEPT_KEYWORDS="~x86" emerge em8300-modules em8300-libraries
To get the stuff installed (dxr3.sourceforge.net for more info). I also added these lines:
/etc/modules.autoload.d/kernel2.6
em8300
bt865
adv717x
/etc/modules.d/em8300
alias char-major-121 em8300
options adv717x pixelport_16bit=0 pixelport_other_pal=0
options em8300 dicom_fix=0 dicom_control=0 dicom_other_pal=0 activate_loopback=1
/etc/conf.d/local.start
/usr/bin/em8300setup
But I am not too sure about the options - and, as you can see, you also have to add i2c to the kernel.
Did anyone manage to get dxr3 to work?
Thanks,
Søren
