Probibly, but I could use certian functions from this code.

This code will enable communications with the Conexant CX25873 tv-out  
chip via i2c through the northbridge GPIO lines. Then I can program  
the tv-out registers and initialize it. I'm still not exactly sure  
where this code will run. If can run before VGA is initialized that  
would be great. But it may have to run after, to get the correct clock  
and timing signals from the northbridge graphics, which means a  
modification to the coreboot core code.
