My suggestion is to use qemu-img to create your virtual disk, instead of 
trying to map directly to your physical drive.
e.g.qemu-img create -f qcow linux-os.img 10G
Then run qemu pointed at your linux-os.img file instead of the physical 
drive. This will side-step all the dmraid pain.
Disclaimer: I don't use windows unless absolutely necessary. I always 
run qemu on linux :)
Also make sure you are also running kqemu assuming it's available for 
windows.

For the record, this would be root=/dev/hda2 in the kernel line of 
/etc/grub.conf
Good luck!
