This particular patch?
We discovered a bug in mini-os that caused 32-bit pygrub to break withi
this series. It's now fixed in mini-os upstream. Check Config.mk for
mini-os commit that fixes the bug.

But this is different from what we found. We need more information.
My wild guess is RHEL5 advertise it supports unmapped initrd but it was
buggy in some way.
