I wasn't able to test this as the HDMI TV I'm using doesn't support this resolution (it is admittedly ~9 years old, the closest resolution it does support is 1280x720@60). How complicated would it be to support multiple resolutions?

Could you try to use these VGA timings to see if your TV can handle it?

    .name           = "HDMI",
    .refresh        = 60,
    .xres           = 640,
    .yres           = 480,
    .pixclock       = 39721,
    .left_margin    = 48,
    .right_margin   = 16,
    .upper_margin   = 33,
    .lower_margin   = 10,
    .hsync_len      = 96,
    .vsync_len      = 2,
    .sync           = 0,
    .vmode          = FB_VMODE_NONINTERLACED

No luck. The TV does support 640x480 when plugged into my laptop,

I did manage to verify with a display that supported 1024x768 and that worked fine.
