Last time I tested: there was no love lost between CSM and S3, independently of video card / driver :) The resume boot path decayed to a reboot. I saw the log and ran screaming. As I wrote in private, perhaps a full Cirrus "reprogramming" could be necessary in the guest, after resume. I had played with that in [PATCH] OvmfPkg: QemuVideoDxe: preliminary S3 boot script for Cirrus VGA http://article.gmane.org/gmane.comp.bios.tianocore.devel/5495 and now I guess the guest might not be able to avoid the full dance (but it should rather happen in the kernel than in OVMF, because OVMF has no clue about the most recent runtime video mode).
