Hello; I seem to be very confused on how to install fglrx on 2.6.25-*
below is the warnings and errors,

Under firegl_public.c it seems the module is requesting a cap_t  get
and receive an effective vector.
With the new capability.h file, what is the capability that replaces cap_t?

cap_t() appears to be defined under ifdef __KERNEL__.  Which makes
sense since it takes a struct kernel_cap_t :)  I don't have the
source code you're compiling, and don't know what would be the "right"
way to fix it, but to get your code to compile I'd just put a
#define cap(x) (x).cap
at the top of the .c files needing it.
