On my old Mac Mini G4 (PowerPC) I am seeing this dmesg output:

It would be nice to either remove this error report as I believe it is erroneous.

Using debian/jessie with:

$ apt-cache policy libdrm-radeon1 libdrm-radeon1: Installé : 2.4.58-2 Candidat : 2.4.58-2 Table de version : *** 2.4.58-2 0 500 http://ftp.fr.debian.org/debian/ jessie/main powerpc Packages 100 /var/lib/dpkg/status

Hi,

actually the "error report" is correct, on PPC platforms there is no BIOS but the hardware is configured via Open Firmware. I've been getting this message for years, it's totally harmless.

By the way: Do you have AGP mode working stable on the Mac Mini G4 ? I've been trying to do that for years with no success :-(
