I'm working on the jffs2 compression issue.  Compression algorithm
support could greatly improve system i/o performance.

We've got partitioning support at ~50% completion (I need to make
modifications to the initramfs initscripts to complete the work).  Among
other things, this will decouple OFW boot functions from the compression
scheme used on the system and user data partitions, allowing us to test
different compression systems.

I keep reminding myself that this is important.  I won't be able to
finish it this week as I'm preparing to go to PerĂº, but will resume work
on it in early September.
