Mmmm, Why for me this two patches don't work?I've tried to apply
manually (as I've done for vt8235-atapi that works) and in automatic
way, but this doesn't work , are you sure that there isn't something
wrong? I've tried to increase the setup timing from 120 up to 400 but
this doesn't work too. It compiles but doesn't work.

Bye
