I didn't see how big the gpxe ROM is.  That might influence which of
these choices you make.

You could:
1. shrink your bootblock (CONFIG_ROM_IMAGE_SIZE)
2. do fallback-only (Remove anything that says normal in
targets/tyan/s2881/s2881/Config.lb)

3. Apply the attached patch (updated version of one that is waiting to
be reviewed.)
