They seem legal in real hardware, even though the EOI is a write-only register. By "legal" I mean they are completely ignored, but at least, don't cause any bits to be set at ESR. Without this patch, some (very recent) linux git trees will fail to boot in i386. This is generated from kvm-userspace, but should apply well to plain qemu too.
Applied, but perhaps a patch to linux to avoid reads to write-only registers is needed as well.
