UML woes in 2.6.24-rc6-mm1

The below patch was needed to make UML compile in latest -mm.

But sometimes it doesn't boot and does weird things (this is a sample
with init=/bin/bash):

[ 0.420000] EXT3-fs: mounted filesystem with ordered data mode.
[ 0.420000] VFS: Mounted root (ext3 filesystem) readonly.
