[gentoo-embedded] can't load ramdisk correctly on nslu2

[Jason]

Ok, I'm frustrated.  :-)

I have the kernel loaded and running via serial/TFTP into an NSLU2.  It
may not be configured correctly (duh), and the kernel command line might
not be correct (also, duh).  I've tried so many variants of the two, I
can't see straight.  I've also tried a gzip'd ramdisk, bzip2'd ramdisk,
and a cpio ramdisk.  Nothing works.  /sbin/init is in the ramdisk.
/dev/console and /dev/null are there also.

I'm missing something basic.  Could someone look over the output below
and point me in the right direction?

I suspect 'invalid compressed format (err=1)' might be a good indicator
of what is wrong, but google isn't being cooperative today.

I'm not touching the flash until I can safely, and repeatably, boot from
ram and run from ram.

thx,

Jason.

PS - I did have this running once before on the same board back in may,
but a hard drive crash taught me a valuable lesson on backups and the
need for them. :-)
