My solution to this (since i'm computer rich and pci-slot poor) is to use VNC to run the SE IV on another box remotely. This gives me some signifigant advantages:
1. it's free (tightVNC is free, at least)
2. It leverages my network
3. I can run SEIV windowed
I'ts a little jerky, but not to bad, it's certainly playable and all that.
