I have the same laptop as you and am happily using ARK-linux.
laptop batterypower etc will not work yet with current kernels.
I hope when the new 2.6 kernel arrives this will work.
So no matter what linux distro you will use, power indication will not work. I can know I tried a lot!
One thing you need to change after install of ark to get sound working is the used sounddriver.
At default it will install ALSA snd-intel8x0 driver in /etc/modules.conf.
Change this to i810_audio and all will work fine
They use a 2.23.pre kernel wich work very very dtable on this laptop. Other linux distro's will hang on boot due to bad SCSI detection. It seems 2.23 solves this.
So, I would go for www.arklinux.com.
For support of this come to #arklinux at freenode.
