QEMU Under Vista

Allright, I'm trying to run QEMU inder windows Vista, and it keeps crashing becasue of vista's FAIL.
So, here are my arguments
qemu.exe -L . -m 256 -boot d -cdrom osx.iso -hda tiger.img -soundhw all -localtime -M pc

Any idea why this doesn't work? It worked under XP, only with less RAM.

Can you name any benefits of 64-bit computing as opposed to 32-bit computing, as they apply to consumer desktops? Didn't think so.
There's a 64-bit Windows XP anyway, and it has better driver support than 64-bit Vista (though still crappier than 32-bit XP or 64-bit Linux).

And DirectX 10 is generally agreed not to be an improvement over DirectX 9. The fact that there still aren't any major games that require DX10 and don't support DX9 is a bit of a hint.
