Could you point out where that was mentioned? I am curious whether anybody has thought of writing a ACPI driver that would parse the ACPI RSDT data or if that is not present fallback to scanning /dev/mem (<shudders>) to extact the iBFT information and present them via /sysfs ? -- Konrad Rzeszutek 1-(978)-392-3903 or 1-(617)-693-1718 IBM on-site partner.
