I have an ATI Technologies Inc 3D Rage Pro 215GP in an Alpha AXPpci33, currently running with MILO as firmware/bootloader. For several reasons I want to change to the original SRM firmware. Unfortunately its intel_cpu/BIOS emulation locks up on the ATI BIOS. With the BIOS disabled the SRM succeeds loading the kernel. fbdev seems to initialize _something_, i.e. the monitor wakes up ans displays a stable repeating pattern of vertical stripes. But it hangs the machine after these lines on serial console: fb0: ATY Mach64 frame buffer device on PCI Installing knfsd (copyright (C) 1996 okir@monad.swb.de). Booting the same kernel image (2.6.[13]) with MILO (which has a different cpu emulation that succeeds executing the BIOS) works fine with fbdev.
