I\'ve been using the 1.4b kernel... and I like it ::: it is more responsive and a little faster then the 1.3 kernel. After I first flashed it, I had the Z lock up a few times ... a soft reset fixed everything with no problems. I haven\'t had it lock up in over a week.
I haven\'t had the problem of the light charging on the cradle... i had it charging last night, and this morning the light was off and I have a full battery. I\'m using revision B 1.4 kernel, and Zynergy 5600 ...
This new kernel also has support for three buttons to turn on the unit... no more accidently having your Z on in your pocket. when you first install it, your screen is reversed an dupside down :-p top right = bottom left .... this is becasue of the japanese writing system, recalibrate the screen, and everything will be fine.
I have had a few problems with the screen being buggy after it has been in suspend for a long time with many instances running nin the background. The front light goes in and out, and once it became disporportional... like wierd lines and things.. Never had it happen again, and I haven\'t been able to duplicate it.
I\'m much happier with this kernel then the 1.3 ... the real linux boot up is GREAT :-D
