My $0.02:  Stop at exactly where you know it's still completely clean and document well (i.e. this email copied into a README somewhere with the distro) what's blocking you.  If you proceed with force, it maligns the goal, here, which was stated as "pristine."  Many, many thanks for the push this far, however!

Ran into trouble with patch 141.  The /usr/src/bin/ld.c file from 2.10.1
is too old; patches from between that and the initial 2.11 are missing,
and the file gets deleted and replaced at a later level of 2.11 patches,
breaking the history.  Patch 141 uncovers the problem.

I can make the patches work, of course - but it means that for much of
the resulting 2.11 history, /usr/src/bin/ld.c will be wrong.
