What command do you use to test?  I can't get pvscsi to work with or
without your patch.  I used this command:

../qemu/qemu-1.7.0/x86_64-softmmu/qemu-system-x86_64 -k en-us -snapshot -L test -chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios -m 512 -device pvscsi,id=pvscsi0 -device scsi-disk,bus=pvscsi0.0,drive=drive0 -drive id=drive0,if=none,file=dos-drivec-new -boot menu=on
