I have been able to build 9ss10 with the above fix and netboot it into 
an SS20 from a PC bootserver but it never appears to gain control.  This 
may be due to my SS20 having an RT625 HyperSPARC CPU rather than a regular 
Sun CPU module, but I really don't know enough about one or the other to
even begin figuring out what's wrong (new cpu vs old cpu?).  The cpus are 
apparently different enough to keep NetBSD/SPARC from working, so perhaps 
in this instance Plan9 is breaking in a similar fashion.  If someone
has run Plan9 on an SS20, what cpu module did you have?

Thanks,
