I created an INSTALL_G5 kernel configuration:

  include "arch/macppc/conf/std.macppc.g5"
  options         MEMORY_DISK_HOOKS
  options         MEMORY_DISK_IS_ROOT     # Force root on ram-disk
  options         MEMORY_DISK_SERVER=0    # no userspace memory disk support
  options         MEMORY_DISK_ROOT_SIZE=6000      # 3000 KiB
  options         MEMORY_DISK_RBFLAGS=RB_SINGLE   # boot in single-user mode

and built a custom -current install CD with that kernel on it as
"netbsd.g5".  I then booted it with

  boot cd:,\ofwboot.xcf netbsd.g5

The kernel started and got as far as attaching genfb, and the screen
switched from black on white to pink (?) on black with a larger font,
but then it got into an endless loop printing these two lines
alternately at great speed:

  [    1.0000000] trap: kernel read DSI trap @ 0x8070200c by 0xff848714 (DSISR 0x40000000, err=14), lr 0xff87a524
  [    1.0000000] Press a key to panic

(this was manually transcribed and so may contain typos).  Pressing a
key did nothing.
