Sorry, seems like nobody got interested in adding S3 emulation to QEMU within the last 6 years, so this is very unlikely going to happen. Thus I'm closing this bug ticket now.

Since 0.12.3 the Cirrus Logic seems no longer working properly (bad font render/corrupted video). Also, S3 is a widely supported device on many OSes and architectures, which will give more compatibility for QEMU. Thanks!
