Kernel headers included from userspace are fundamentally broken. W/ 
2.6.10 you _CANNOT_ build hal using kernel headers. For example you can 
find the following lines in the 
/usr/include/linux-2.6.10/include/linux/list.h:

#ifdef __KERNEL__
.... /* define some useful stuff */
#else
#warning "don't include kernel headers in userspace"
#endif /* __KERNEL__ */

The solution you needed is called linux-libc-headers (in some 
distributions they're called glibc-kernheaders, glibc-kernelheaders):

I found headers for 2.6 kernel in PLD (Polish Linux distribution): 
http://ep09.pld-linux.org/~mmazur/linux-libc-headers/. You can also 
check http://rpm.pbone.net for their RPMs of the package. I built HAL w/ 
them (linux-libc-headers-2.6.10.0) and it works /almost fine/ for me 
(minor bugs I described so far are unlikely caused by those headers).
