kernel modules not stripped?

[dragoran]

I have read a thread on lkml about stripped and not stripped modules... 
so I checked if they are in fedora (2.6.21-1.3194.fc7) and it seems that 
they aren't.
so I tested how much it would gain (size) so I picked some random module 
(sata_nv.ko) copied it to my home folder and did the test:
original size: 40512
stripped size: 26912
so it seems that we are wasting ~50% of space by not doing this.
reason for this?
note: this was on x86_64
