I don't know things on other distributions mostly at all; I've read Ubuntu's scripts really a little bit only. I'd like anyone to post patches if necessary... BTW, what's the status of this patch set? I've redesigned this so as to be done with kernel parameter in order not to depend on platform specific BIOS table. Due to the redesign, I think now ACK is needed again. -- Thanks.
