So I gave the most updated version of this Kernel a try since the dev seems to have ironed out most of the bugs... I must say I think he's nailed the trickle charge issue with the EVO.
I, for the first time, left my EVO on the charger all night. Unlike before, I didn't have it drop from 100% to like 90 within 10 minutes of just sitting idle. The phone has been idle for about an hour and still sitting pretty at 100% without so much as a hiccup.
He is using the netarchy kernel as a base so it is also overclocked to 1267mhz and running like an absolute champ with VaelPak.
I'd recommend this kernel to anyone out there tired of having to take the EVO off the charger at exactly 100% to get good battery life. This also supports extended batteries.
