As far as I know, there's no FPU on the S3C2416.

The S3C2416 has an ARM926EJ core. I'm fairly sure it has VFP since HP's own firmware has lots of VFP instructions inside armfir.elf (well, they could trap and fallback to softfp emulation, but I do hope they haven't done something that backwards). It's just that by the time PRIME_OS.ROM runs, VFP hasn't been enabled yet and I was not in the mood to meddle with black magic processor state.
