That's no longer the big time item. The big time item is now the
decompress, which seems to run
at 4 kilobytes per second.

we can just put the option in kconfig. we had this option in v2.

The LX does not have the kind of clean breakdown of components we are
used to on other systems. I don't think you can say geodelxinit is
"northbridge specific" or not. I am happy to move it back to the
northbridge directory and just link it in.

We've got to run this in stage1 IMHO. We can't wait until stage2 phase
2 to turn on cache. It's just way too slow.
