I've actually gotten the improbable to work, and am PXE booting via
syslinux and dhcp.

It all works fine with an initramfs of ~20 MB, but that's quite a diff.
from 2.7 GB of expanded /root (890 MB cpio.tar.gz file).

But excuse my ignorance, I don't see the relevance of your
question...the initramfs is part of the kernel itself...I simply load
the kernel bzImage (all 890 MB) and that's where its all at...this is
_not_ an initrd.
