Just to clarify, my "definitely easier for me" means "I know what to
do (or, at least, I'm closer this way not doing wrong things)".

Just for the record, I have grabbed your for-pci2 branch with HEAD
being 5db4211 and this is what I get:

    http://www.ime.usp.br/~rbrito/linux/clevo/boot-yinghai-for-pci2-g5db4211.m4v

A warning, though is that there were some options regarding PCI buses
which I did not know exactly how to answer. I can post my config here
if you are interested in that. Well, actually, I can give you ssh
access to this notebook if you want to hack on it. Just let me know
what times you (or anyone else) are online and I will try to arrange
everything.

Any guidance is welcome.


Thanks,
