Thanks for all the responses, I got it working.  I downloading a v2.4.6 off
a thirdparty website, FTPed it to my linux box, downloaded a tftp client,
turned on tftp on the 678 and set my IP as the remote address.

Then I just put the file from tftp and all was grand.  One kicker was that I
had to the set "mode" on the tftp to binary before the cisco would accept
the file.  That took me about 5 failed transfer attempts before I checked
the "show error" on the 678 which told me what to do.

Thanks guys!

Mike
