Below is the answer of the GLIBC maintainer.
It appears that these bugs are instances of bug #521863
against the Linux kernel. This bug will be fixed in
2.6.26-2-amd64 for lenny and 2.6.29-1-amd64 for sid.
I will let the bugs open so other affected users can see.
Please close your bug once you have updated your kernel
and confirmed this fix the issue.
Thanks for your cooperation with handling this problem!
Cheers,

It's a know kernel problem for i386 installations with an amd64 kernel.
Possible solutions:
- install kernel linux-image-2.6.29-1-amd64
- install linux-image-2.6.26-1-amd64 from stable-proposed-updates
Possible workarounds
- install an i386 kernel
- install libc6-i386
Reassigning an merging the bug.
