Build Identifier: 

The ivtv ebuild checks for various kernel configuration options, but not for
CONFIG_KMOD which is required as stated at
http://ivtvdriver.org/index.php/Howto#Kernel_configuration_specifics

Reproducible: Always

Steps to Reproduce:
1. Disable CONFIG_KMOD, build kernel, reboot
2. modprobe ivtv will give you failed to load module tuner i.e

Actual Results:  
ivtv not working correctly

Expected Results:  
Checked for CONFIG_KMOD

Fixed ebuild for 0.8.0

Dup of #149039?

You are actually incorrect. It does not require KMOD at all. KMOD is a method
by which other kernel modules can request features from the kernel. The current
running kernel might not have that feature available so it queries for a module
that provides that feature and then it loads that module. You can very simply
load the proper and appropirate modules for your kernel without needing this
enabled. In fact many users who have problems with this feature (i.e. the wrong
module or wrong feature is loaded) disable KMOD and load items themselves.

However, this feature is enabled by default in kernel configs and the help
selection says it's strongly advised you leave it enabled. Clearly this is a
clear cut example of someone not understanding options and flicking on and off
switches that they are clueless about. And then not understanding what they did
wrong.

Well, this may be true, it runs without the KMOD option if you load all the
required modules by hand. On the other side the ivtv developers recommend to
enable the option... but I'm ok with your decision.
