good news! I'll try to test that asap.

Andrey,
I currently failed to downgrade.
Does that mean this mode should work in 7.1.x firmware? or things
are less likely to break?

Michael,
I will need to test the code some more (current version is really
experimental and have some glitches), but it seems that the lines can
mode is back in 8.0.6.6 firmware. It supports up to 16K of lines in each
composite frame (frames are supposed to perfectly match - no gaps
between them). With full line of 2592 pixels the regular 5MPix sensor of
the 353 camera can handle about 2500 line pairs (they go in pairs as the
sensor is color) per second.
The same mode should be useful to get the top fps for small images
avoiding the CPU overhead related to the file headers and just
processing the frame interrupts. It is possible now to combine multiple
small images (not just 2-line rectangles) to the total height of up to
16K lines in a single composite image.
Here are some samples (original and some - rotated/cropped):

It is fun that cars going in the opposite directions on the freeway are
going the same direction on the image. You may also notice something
like huge chromatic aberration - it is caused by the car crossing one of
the line in a color pair before the other.
Many images are acquired at reduced rate (they have "582lps" in the
name) so the cars look more proportional, at the full 2425 lp/s they
look too long.
