Old hardware with old software but have you tried updating the software
to at least a 2.6 kernel (Etch, Lenny or Squeeze?)

Static linking is not fully supported in Debian and therefore Emdebian.
Sometimes it might work, sometimes it will fail, sometimes it will run
but give you mysterious issues... "behaviour is undefined".

Then why bother with static linking in the first place?
ia64 packages still exist in Debian, so why stick with the old
versions? Replace what you have with updated packages. Older versions
will be available via archive.debian.org.

You'd have to get a backtrace via gdb. If static linking doesn't work
but dynamic does, there aren't going to be many people in Debian who
will care.
