[syslinux] Soekris net45xx initialization hang

I'm working with a Soekris net45xx SBC and I'm experiencing problems
using any syslinux code (syslinux, pxelinux, extlinux) above version
2.20. I'm interfacing with the Soekris via the serial console port,
which is the primary bios console. I've tried different configurations
with setting serial in the config file, but no change (though I dont
even thing it's getting to reading the config file, see below). I've
confirmed that I experience the same symptoms at 2.20-pre14 and all
versions above. I did not test any version before that as I need to use
extlinux. Enough with the setup, on to the show:

The system boots fine and loads the code off sector 0 without fail. It
displays (for example)

SYSLINUX 2.20 2.20-pre14

Then does nothing. I dont even get the copyright, which after examining
the assembly, is the next thing written out after the header. I dont
believe that it's even getting to loading the configuration file. Has
anyone else experienced this? I've had all previous versions work fine
and something seems to have changed in 2.20+ that his blocking these
boxes from working. I have the latest soekris firmware and I've
confirmed that the terminal emulator I'm using is operating correctly.

Thanks for the help.
