Linux BIOS CPU support for the K8 ( Athlon X2) is complete and working 
on many systems. The problem with the AcerT180 is the support for the 
NVidia 6100 chipset (MCP51?).  It might be close enough to the MCP55 but 
that is the biggest hurdle using this platform. Here is the list of 
supported devices:

You would need to examine the board and see if the ROM is socketed. Here 
are some details:

The 82810 chipset is listed as supported. There are several people 
working on Intel ports. They might have more information.
Here is the list of supported motherboards.

I don't know. I am not familiar with the PowerPC socket requirements.

Thanks for your interest in LinuxBIOS. I have copied the LinuxBIOS list 
so you can get the support of the entire community. The list is the best 
place to solicit support from people working on similar platforms and to 
discuss the problems you find as you transition to LinuxBIOS.
