I bought a Pansonic CF-25LJM8EAM notebook. 
All important chips on the mainboard are listed here:

Bari, can you spot which one is the "keyboard controller" which you 
said is usually the critical problem on getting LinuxBIOS to a laptop?

The chipset is supported (Intel TX).

What are the chances of getting this to work?

The BIOS flash is unfortunately soldered, but I thing of giving the 
mainboard to an electronics facility so they can desolder it and 
solder a socket there.

Interesting, the CPU is in a socket, so it might be possible to mount 
a AMD K6-2 350 MHz. It is possible on other Intel 430TX motherboards 
after binary patching the BIOS. Here is a site with binary patches for
such BIOSes in many motherboards:
