the mechanism has now been fixed and all assignments
in plan9.ini become replacable parameters.  a $ is used to
indicate a variable indirection.  9load will assign bootdev
and bootpath automaticly as a convience.  e.g. sdE0 and
#S/sdE0.  our previous example should now read
        venti=$bootpath/venti
(the previous example will temporarly be accepted.)

there are a few other things along for the ride.

if you are using 9load menus, you can add 9load variables
by typing them in like this at the menu prompt.
        a console=0 b19200
one could remove the debug option from the 9atom cd
knowing that one could always enter
        a *debug=1
at the menu.

added bonus: small corrections to the e820 scan.
