[Kernels] 3/24/11 - Froyo/Gingerbread
This is the same series of kernels present starting with SS 5.2 - the benefit of these kernels over my others is that (by default) logging is disabled. You can turn on logging by using the logging.ko that is present in the zip, which will go to /system/lib/modules with the others. However - unless you need to debug (ie. run a logcat) it is just taking up precious power.
And YES - these will work for both Froyo AND Gingerbread. Included in the zips are most common filesystem drivers as well. If you do not know what they are, you do not need them ;)
Standard rules apply - if you load up, and get stuck at the 'M' - first wipe CACHE. If still stuck - try a different kernel.
Compcache is supported within these kernels - however, if you are using a non-SS ROM and have problems - you need to speak with that ROM's dev, as most of the work for compcache is in the ROM itself.
