I couldn't figure out how to do that using the Open Firmware boot loader --- it
doesn't understand sysctl, AFAICT.  I tried the -d kernel switch but it didn't
change anything.

This machine lacks a serial port, which makes traditional kernel debugging
difficult.  I noticed that its Open Firmware version does support telnet
connections, though.  Is there a way to use that facility for a kernel debug
console?
