I have tried it without kvm and bug repeated: ./build/x86_64-softmmu/qemu-system-x86_64 -chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios -m 512 -hda tmp/xp.append -hdb tmp/data.append

Kevin, did you repeat screen mess?
I've tried several different configurations (including the last command line you sent), but I have not been able to reproduce any screen corruption.
I have repeated it at every time on server, my laptop or my pc. I tried it on ubuntu 14.04, centos 6.5, kernel 3.10.67 and kernel.3.16.0.36 etc. What is the difference? I used guest os is xp sp3. What yours? I will try again with environment same as yours.
I'm using "Windows XP professional - Service Pack 3".
To simplify versions, can you use the latest QEMU - 2.3.0-rc4 and use the seabios and seavgabios that come with that version of qemu. I tested that here and don't see corruption with those versions. This is the command line I used:
../qemu/qemu-git/x86_64-softmmu/qemu-system-x86_64 -chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios -m 512 -hda winxp-test-wbc -enable-kvm
Also, for completeness, try it without kvm as well:
../qemu/qemu-git/x86_64-softmmu/qemu-system-x86_64 -chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios -m 512 -hda winxp-test-wbc
