Are Kernels flashed to a separate partition on a Galaxy Fit?
A: Yes, a ROM does overwrite any kernel that was previously installed.
B: No, it isn't kept on a separate partition. It's in the boot.img.
You can always re-flash the kernel you want after you install the new ROM, most should be cross-compatible. Well, you can not mix CM7 with CM10 and etc. naturally. But you should be able to flash diferent GB Kernels on GB.
Also, if you do mess it up. Its easily fixable. Since its only the boot.img, its no big deal, since every ROM has one integrated, just flashing a new ROM or Kernel will fix it =)
