This is a bit of a hack, but currently the only + way to make room for the Etherboot features that need substantial amounts + of code like the ANSI console support.

My + interpretation of this "reserved" is that Etherboot may do whatever it + likes, as long as its environment is kept intact (like the BIOS + variables). Hopefully fixed rtl_poll() once and for all. The symptoms + were that if Etherboot was left at the boot menu for several minutes, the + first eth_poll failed. Seems like I am the only person who does this. + First of all I fixed the debugging code and then set out for a long bug + hunting session.
