I was able to get the driver working with this hack to bypass the hardware check:

Make sure you use the appropriate package name.
Tip: If you use TextEdit,
DO NOT save the Distribution file (cmd-s). Just click the red close button and let TextEdit do it's thing.
What I did:
Graphics card (EVGA nVidia GTX 750 Ti) is not installed at this point. I am using the onboard graphics at this point.
1. Create the installer package using above method.
2. Click the package icon to start the installer.
3. Installer does it's thing.
4. Reboot computer.
5. Confirm drivers have been installed by opening "System Preferences". nVidia panel should be at the bottom.
6. Shut down computer and turn off power supply.
7. Installed graphics card. Still using onboard graphics at this point
8. Power up and boot computer to confirm that the computer will boot without issues. So far so good.
9. Reboot computer and hold hotkey (delete) to enter BIOS.
10. Set initial display to PCIe 1 (slot my card is in).
11. Save settings and exit, letting boot process via Clover to continue. Still connected to onboard graphics.
12. Confirm that I have booted successfully into OS X 10.10.2 with nVidia preference pane installed and the nVidia driver is selected.
13. Shutdown and power off computer.
14. Connect monitor to card via DVI.
15. Power on and boot computer.
16. Computer boots successfully and and all is well at the moment.
At this point I shut down and connected via HDMI just confirm it was working. It was fine, at least the video was. I have no way to check the sound.
