64-bit 12.2 on a Lenovo W520 with NVIDIA Quadro 2000

I had been running the 32-bit release candidates on this same laptop without issue using the nouveau driver. When RC2 came out I decided to try the latest NVIDIA proprietary driver and was surprised that I got it to work. Now with 12.2 formally released, I decided to try the 64-bit version of 12.2. I wasn’t even able to boot the installation DVD with the BIOS set to use the NVIDIA card, I had to switch to the Intel card (Integrated). Any attempt to use the NVIDIA only BIOS option (Discrete) results in the boot process hanging.

Anyone have any suggestions?

Thanks in advance
