In the case of SeaBIOS as a fallback payload, there is one more thing
to take care of:
The user must take care of making sure that what the fallback SeaBIOS
loads automatically doesn't prevent it to boot:
For instance if the user add some option rom in cbfs intended for the
normal SeaBIOS and that it also prevent the fallback SeaBIOS from
booting it would be a big problem...
The workarround for that case is to configure (make menuconfig) the
fallback SeaBIOS not to load option rom for instance. Of course that
would need to be tested first...For instance by making the current
payload load the modified SeaBIOS...

Great idea.

I've already figured the pxerom from the factory bios doesn't run on
coreboot, seems to expect something coreboot doesn't provide, complains
about some missing ID.

So I wanna add a ipxe rom instead.  And having a fallback plan for a
broken ipxe rom is good ...
