Ok, that fix works, thanks. And the .lzrom version has no problem with
loading to 0x20000. The 3c509 is a nice card to start with as it only
uses I/O instructions. There is a small glitch though. After the second
bootloader runs, sometimes it's unable to find the NIC the next time
around and has to wait for a full reset.

Slightly related, but in main.c there's a static int card_retries = 0
which will not be reset by a longjmp. Probably needs to be made
non-static and (re)set to 0 during initialisation.
