Tinycore is here 12/1/2008! Welcome visitors.
If you are just trying to test old kernel on the new alsa, etc. And you are not comfortable compiling. It would be easy to copy the 13.1 kernel onto the new image.1) Boot your 13.1 image.2) Mount a new SD card with the 14.0 image.3) Copy the kernels and module initrds from the 13.1 boot partition to the 14.0 boot partition4) Copy any kernel module extensions from the 13.1 /mnt/mmcblk0p2/tce/optional directory to the 14.0 image in the same location.5) edit config.txt on the 14.0 image to reference the old kernel files.
I never said to copy the entire optional directory. Just the extensions with the 5.10.77 kernel modules.
