Im using Gentoo Linux with sys-kernel/linux-headers-2.6.21 and
the kernel sys-kernel/gentoo-sources-2.6.22-r4 (== 2.6.22.3 + Gentoo specific
patches)

I found a definition of elf_fpregset_t within incluce files from the glibc
package:

tfoerste@n22 /usr/include $ grep -Hir user_i387_struct *

tfoerste@n22 /usr/include $ grep -Hir elf_fpregset_t *
sys/procfs.h:typedef struct user_fpregs_struct elf_fpregset_t;
sys/procfs.h:typedef elf_fpregset_t prfpregset_t;

tfoerste@n22 /usr/include $ equery b sys/procfs.h
[ Searching for file(s) sys/procfs.h in *... ]
sys-libs/glibc-2.5-r4 (/usr/include/sys/procfs.h)
