The key isn't locked to a drive, but there is a hard drive model check in Force 2004. The game reads the model from /proc/ide/ide0/hda/model, so it's easy to bypass.
Adding something like this in a boot script should do the trick:
echo MERIT0011 > /tmp/hd
mount -n -o bind /tmp/hd /proc/ide/ide0/hda/model
