PowerMac G4 933MHz agp slot. I have Debian 5.x and FreeBSD 9.0 on the machine. The modules of agp and drm build only from current. With agp, this is not a problem; however, drm will not build due to a dependency on x86. Discussions on the freebsd-ppc mailing lists state that drm is unstable. The machine came with a Matrox card and the standard radeon. There is support for the Matrox with both OSes but I do not know how to switch the default graphics card in OpenFirmware. How do I do this from the forth prompt?
