I suggest to just downport the tulip patch.
32-bit currently works in stable series as-is.

Most current fixes in SeaBIOS and hppa code are to fix & enable the 64-bit
Linux kernel & HP-UX. I don't think we want to completely back port those,
as they aren't yet fully functional either. So, this 64-bit is stuff which
should be limited to upcoming versions.

In case we want the newer SeaBIOS in stable, I suggest to additionally downport:
- target/hppa: Add "diag 0x101" for console output support
- target/hppa: Update SeaBIOS-hppa to version 16 (minus the 64-bit binary)
