Hey,
I'm not sure exactly whats going on with the firmware. Unfortunately, we don't have an active maintainer for that code right now. Simon wrote most of it, but he's been quiet lately.
I started tagging releases in subversion a while back, so you may want to try building the sources in /tags/firmware/1.0
here are the changes since the last release (on May 29, 2007). My guess is that its now building from the current SDCC version that is making the binaries different.
perhaps its time to do a new release. are there any firmware gurus out there that want to be the release maintainer for the firmware? there may be some free PCBs in it for you. =)

extruder changed to extruder_0_ and extruder_1_ added.
At the moment the two are identical, but extruder_1_
will become the paste extruder controller.

Started to develop code for multiple extruders:
Extruder_1 is a simple on-off solenoid (for the coke
bottle/balloon extruder) at address 9.
