First, I do need to clear up one misimpression: it used to be true that
you really couldn't run linuxbios out of 256K. Eric and Steve have changed
that in different ways.
First, Eric can now have the standard etherboot package as a payload.
Second, Steve has made it possible for linuxbios to do etherboot directly.
So you can't have a linux payload (I don't think) in linuxbios in 256KB.
On to the other problems.

yikes. That sucks. More vendor braindamage.

Because you can use a Disk On Chip, and that will work just fine in this
socket. It doesn't even have A13->A19 wired internally. Just A0->A12.
