Hi Curt,
Unfortunately, I don't see anything in the log that looks suspicious.
Since you are using qemu/kvm, you could try attaching a debugger (if
you are familiar with gdb).
There's documentation online and in the SeaBIOS' README file. In a
nutshell, run qemu with "-s -S" and then run "gdb" in another terminal
and send it "target remote localhost:1234" along with something like
"br *0x40000" to set a break point at the start of the payload.
Another option would be to try with a known working payload and verify
if you can get SeaBIOS to launch it.
