NTSC with just PAL chroma frequency is called NTSC-443. PAL-60 also uses 
PAL color encoding.

I could probably implement other TV standards in the driver since the 
only thing that should need changing is the chroma frequency.

PAL-M = PAL-60 with 3.57561149 MHz chroma frequency
PAL-N = PAL with 3.58205625 MHz chroma frequency
NTSC-443 = NTSC with 4.43361875 MHz chroma frequency

Any need for those?

The screen API already has support for TV standards. Currently listed 
standards are PAL, NTSC, SECAM and now PAL-60. Others can be added.

I haven't really looked at the API so I don't know what (if anything) is 
missing.
