xserver build failure from lnx_agp.c

[dave frost]

everyhting builds fine up to this point on the 'xserver' build section. 
mesa also builds and installs fine.  I think this must be an issue with 
my linux kernel includes possibly ? im running kernel 2.6.16 and i dont 
have the usual /usr/src/linux symlink, is this important ?

thanks for any help.

cheers

Dave
