Thanks, I went through the references..
The distcc-crossdev approach seems to assume that
all of the upgrade actions start from the slow machine
but get executed on the fast system. And there is no
saving of the intermediate results (binary packages)
On the mythtv machine there is a spare partition
created for testing. I am thinking of the following
approach
- create all the binary packages
- NFS mount the spare partition
- install the binary packages and boot up with
the spare partition for testing.
This should leave the mythtv system with a working
setup all the time. In this case, how do I bootstrap
the spare partition ? Should I start with the gentoo
livecd or do a 'dd' from the working partition to the
spare one ?

In my case it is the stability..the safe cflags gentoo doc
is indicating that "march=c3..." so this probably means cross
compilation.
