The mouse was fixed in devel by Yin Sun. I will copy his code next.

I don't know why you have this error. I can only say, that the patches 
and config in source of coLinux version 0.7.7.1 can clean build kernel 
2.6.26.8, used gcc 4.4.1
Please try to remove or rename the both directories 
linux-2.6.26.8-source and linux-2.6.26.8-build. Than start a fresh build 
with default config.

Yes, PCI is essential for networking.
