Excellent! 

So it should be noted somewhere in the NetBSD docs, at least until
something more formal can be implemented, that calling set-dfs-high
before booting will enable full CPU speed on TiPBs.

Since instructions in Forth can be stacked, something like

dev /cpus/PowerPC,G4 set-dfs-high boot hd:9,\ofwboot.xcf netbsd

should work for booting (after replacing partition info as appropriate).

Now it'd be nice to figure out how a CPU that has an unrecognized
version will get the CPU speed measured, as well as having an L2
cache listed.
