i believe upstream ships gPXE roms in recent versions (at least, if qemu-kvm is
following qemu). we will hopefully have uploaded gPXE to NEW before the end of
debcconf.

correct. to be clear, the etherboot roms are identical to the corresponding
compressed roms shipped in the full package.

nobody has proposed patches to qemu or qemu-kvm to handle that, as far as i
know.

etherboot-qemu is already in the archive, so it has already been introduced.

depending on etherboot-qemu works better than shipping whatever roms happen to
be in the etherboot package at qemu-kvm build time, which is the current state.

it honestly seems a simpler approach to me to have a package that ships a
smaller number of uncompressed roms than patching qemu/qemu-kvm to support
compressed roms and is *trivial* to implement given that etherboot-qemu is
already in the archive.
