I have running tKc rom with the Cacko kernel update, for about a week now and I have the blinking battery light issue, but it is very sporatic. Sometimes it goes for day without happening and once it does, I just disconnect the power and reconnect it, sometimes once does it, sometimes it take two or three times. Sometimes it needs to be suspended, sometimes not. Not anywhere near a deal breaker. Not ever that much of a annoyance. The speed is much better and I can open more progs at a time without crashing. I often have Beiks English Dictionary Pro, QPsword, Opera and Opie Reader open at once and maybe check the Calendar (KOPI) in the midst of it all. Qpdf2 is a little slow to open (I tried to install " t1lib_5.0.2-r0_arm.ipk to do the fix that someone posted elsewhere, but the file doesn't work. Maybe it's not for sl5500???), but everything else opens and moves faster. I had originally tried it with 64-0 Cacko rom, but i did something wrong. I kind of want to try it again, but this is working so nicely, I hate to mess with it (at least for a while). Thanks Maslovsky.
