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)". >>> When I compiled from your branch for-pci2 from linux-yinghai.git (without >>> any extra patches), it *did* boot, but noticed one thing weird: using htop >>> and in single user mode, it reported 100% of CPU in use.

Will try that as soon as my download completes. 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.
