What you have experienced are kernel panics. These are unrecoverable errors encountered by the Mac OS. I wouldn't be so sure you don't have any hardware problems - in my experience, 80+% of kernel panics, especially repeated panics like you're getting, are caused by hardware.
Have you run the Apple Hardware Test function on your Mac?
Have you run a program such as MemTest to make sure your RAM is functioning correctly?
Have you tried running a general hardware diagnostic with a program such as TechTool Pro - one you can boot from CD/DVD?
Have you booted from the Mac OS X install disc, run Disk Utility, and checked your disk for file system errors?
These are all things I would try, not necessarily in the order I listed them.

I had similar problems with a g4 powerbook last year and it turned out to be the battery (even when plugged into the mains)
see if you can borrow a battery from someone and try it out

Anyone help me out?
yes, just unscrew the plate.
To remove the ram there are small clips on the edges of the RAM all you need to do is spread them out and the RAM will pop up. Then it is safe to remove.
Most RAM is covered under lifetime warranty from the manufacturer (with Apple RAM from the factory, that's usually Samsung or Micron from my experience) so you can probably contact Apple even if the powerbook is out of warranty, they should be able to either honor the manufacturer warranty, or point you in the direction of how to contact the manufacturer to get a replacement.
If the RAM that is bad is RAM you put in, then contact the manufacturer directly.
