after decompression:
$ file TBOOT.B00
TBOOT.B00: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
statically linked, stripped
$ file tboot
tboot: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
statically linked, stripped

Tried the 32 bit kernel for testing?  I'll spin up a few tests shortly.
