I changed a bit by adding more error checking, and pushed to the same branch.
now its hash code is cc7783a.
Another question, the main fix for the bug, which is the commit below,
is pushed to master.
Can I cherry-pick this commit to branch sid? Thanks!

[armel] Disable CONFIG_STRICT_KERNEL_RWX
This will save about 3MB on linux Image (before compression).
u-boot loader on some armel devices has limitation that:
- kernel image size <= 2MB (already described in
debian/config/armel/defines)
- kernel size after decompression <= 7MB
