The gdt address calculation in linuxboot.bin is broken in two ways: first

With these issues fixed, linuxboot works again.
Wow, I wonder how it worked for me...
Got it.  The option roms are built in pc-bios/optionrom, but QEMU loads
the ones in pc-bios.  So actually I was always testing Alexander's code
even though I had done a "make -B" to feel safer. :-(

This will wreak havoc on the tree since these are built by default and they are replacing files in revision control.
