Looks as fixed in grep-2.6.1 in rawhide. I am going to push it as regular
update to all suported versions of Fedora.
$ time grep foobar /usr/lib/locale/locale-archive
real 0m1.410s
user 0m0.199s
sys 0m0.178s
$ time grep -i foobar /usr/lib/locale/locale-archive
real 0m4.504s
user 0m4.374s
sys 0m0.043s
$ time fgrep -i foobar /usr/lib/locale/locale-archive
real 0m4.422s
user 0m4.280s
sys 0m0.036s

This problem still exists.
It affects both x86_64 kernels running i386 programs and i386 kernels.
As GDB has default "set disable-randomization on" for reproducible debugging
sessions this feature does not work for 32bit programs/platform.
Tested:
kernel-2.6.33.1-19.fc13.i686
kernel-2.6.32.9-70.fc12.x86_64
(set -x; for i in -m64 -m32;do gcc $i -o ADDR_NO_RANDOMIZE ADDR_NO_RANDOMIZE.c
-Wall -g -fPIE -pie && ./ADDR_NO_RANDOMIZE; done)
+ gcc -m64 -o ADDR_NO_RANDOMIZE ADDR_NO_RANDOMIZE.c -Wall -g -fPIE -pie
nonrandom3: OK
+ gcc -m32 -o ADDR_NO_RANDOMIZE ADDR_NO_RANDOMIZE.c -Wall -g -fPIE -pie
nonrandom2: Even with ADDR_NO_RANDOMIZE: prev 0x48d82c vs. now 0xb4882c
