I haven't played with it recently but I recall the issue before was
that our pxeboot is relatively huge (since it includes /boot/loader)
and Etherboot runs out of memory that it can address.

It might be interesting to see how Etherboot worked a long time ago
with some patches to it and pxeboot to make it work.  This was before
PXE support was added to Etherboot.  Also things could have changed
in Etherboot since the last time I tried to run pxeboot with it.
