[edit] Introduction
First of all, I have to disappoint you: this won't work with Kernel-2.6 (yet)!
My configuration:
- kernel-2.4.26-gentoo-r2
- i2c-2.8.4
- lm-sensors-2.8.6
- gcc-3.3.3-r6
- glibc-2.3.3.20040420
[edit] Let's Get Started
First, you need to remove all i2c support from your kernel:
cd /usr/src/linux make menuconfig
Go to: Character devices/I2C support/ Disable everything! Then delete the i2c modules:
rm -fr /lib/modules/`uname -r`/kernel/drivers/i2c/*
Also unmerge all versions of i2c and lm-sensors:
emerge -C i2c lm-sensors
Then go to the correct directories in the portage and install the newest versions. It is very import to do it this way, just emerging i2c and lm-sensors will not install the newest versions though ebuilds for newer versions do exist: I don't know why!
First, emerge i2c:
cd /usr/portage/sys-apps/i2c emerge i2c-2.8.4.ebuild
Then do:
modules-update
Then emerge lm-sensors:
cd /usr/portage/sys-apps/lm-sensors emerge lm-sensors-2.8.6.ebuild
Then:
modules-update
Ok, it should have installed with no problems. Now go to the "Monitor" Section in your /etc/X11/XF86Config and add these Modelines:
ModeLine "640x480PAL" 29.50 640 675 678 944 480 530 535 625 ModeLine "800x600PAL" 36.00 800 818 820 960 600 653 655 750
then search for the "Display" Subsection, and add:
Modes "800x600PAL"
Save the file as /etc/X11/XF86Config.TV
Now create a file you use to start your TV-Out:
| File: /bin/startv |
#!/bin/bash
# -Craig-'s TV enable script for Voodoo3 3000 AGP
# 04-06-25

You can save the script as /bin/startv, then you just have to enter startx for normal work oder startv if you want to watch a film on TV. The scripts is quick'n'dirty, I know...I am working on it and will add more error checking in the future!
EDIT: Error checking added to the script! The output of the script looks like:
| Code: startv output |

i2c-core.o found, loading...ok
