This is a very timely question. First let me clarify that what we're really talking about here is the difference between the slayher kernels made for LFYv1.5 (which are not the same as the slayher v1.5 kernels) and the slayher v1.6 kernels.
HERE IS THE IMPORTANT INFO: If you installed a slayher v1.6 kernel on LFY 1.5, and you downloaded that kernel before the time of this post , then compcache will not work for you -- even if you go back and install one of the slayher kernels made for LFY 1.5.
So, here's the deal. This morning, I wanted to see if the compcache would automatically be enabled on the slayher 1100 v1.6 kernel posted in his CM thread. I installed it, went to SetCPU info and saw 0 for all the swap entries, then went to my script for compcache stats in GScript (which I had tested many times in the last 2 days -- and which is exactly the same script quoted above) and got the response "not a typewriter." SO, I reinstalled the slayher LFY 1100 and got exactly the same results. I then restored my boot partition from before I tried any of this (the exact same setup on which the compcache stats worked before) and still got the message "not a typewriter." Of course, this led to the conclusion that not only is compcache not automatically enabled on LFY for the slayher v.1.6 kernels, but once you install one, it screws up compcache entirely for all subsequent kernel installs.
I reported this to slayher and he thanked me for calling it to his attention, said that he had packaged some scripts with the v1.6 kernels to get compcache working for CM and that those scripts are conflicting with LFY (and, in fact, changed the scripts in the ROM that were included to enable compcache).
If you made the same mistake I did, then in order to get compcache back, you will need to reinstall LFY 1.5 and the slayher kernel of your choice (no need to wipe data and cache, but you do need to reinstall the ROM).
The GOOD NEWS is that slayher immediately fixed the v1.6 kernels and re-uploaded them, so this should not be an issue for anyone wanting to try any v1.6 kernels downloaded for here on (see here: Froyo Kernels by slayher - CyanogenMod Forum - Page 7).
Slayher, if you read this, please correct anything I may have gotten wrong!
Ok, I think I got it now... So I will reflash my rom without wiping cache and data... And delete any old kernels I have so as not to use them.
So should I be using the new fixed 1.6 kernels or the ones made for LFY 1.5?
Just link me please to which ever ones I should be using and I'll install those...
Thank you for such an informative post...
