Oh, my bad.  Updated the wiki page to reflect your statements.  And I
completely forgot about lkrn!

So once the patch is in gPXE, it would look something like this?

label sanbootex01
  MENU LABEL [^iscsi] Boot from SAN
  kernel gpxe.lkrn
  append root-path=iscsi:192.168.0.1:
:::iqn.2006-09.com.example.myhost:storage
