A solution that I can see is adding DMA boot capabilities to the
linuxboot.S optionrom. I was trying to avoid this, but it looks like
not doing so creates lots of problems. It may be better than adding a
"nice" shortcut somewhere in QEMU or SeaBIOS.
Who uses this optionrom (and will benefit from this change)?
