Havn't looked at the qemu side too close yet, but as I understand things
the firmware programs the ECAM location (simliar to the q35 mmconf bar),
and this is just a limitation of the current seabios patch.

So, no, *that* part wouldn't be messy in ovmf, you can simply place the
ECAMs where you want.
