Oooh, I can sympathize here. :) What you'll need to do is get a
server which is capable of running tftp. FTP to ftp.livingston.com and
grab one of the GENERIC kernels from them, and and put it on your tftp
server as

/tftpboot/GENERIC.PM2

Then add a route for your portmaster's hadware interface by:

rarp -s your.portmaster.name 0:c0:5:1:26:51

This will enable your portmaster to net boot off of your tftp server.
(Be sure it's world readable, yada, yada, yada).

Your portmaster will then boot. Sort of. It'll boot with a generic
kernel that sucks rocks and you won't really be able to use it, nor will
you be able to upgrade it. You'll need to reset the flash in it by
telnetting to it, logging on as !root, and typing

set reg 0xFFF 0xF63

(This will completely wipe the flash ram of your portmaster, _including
the configuration_. You did use pmreadconf to backup your configuration,
didn't you? :)

You now have a basically virgin portmaster.. upgrade it back to the comOS
you want and you should be okay. Feel free to talk angio@aros.net if you
get this while I'm still around, and good luck.
