There are some patches floating around; I'll have a little bit more
in a little bit more than a week and will try to fix the bug.

No surprise. I had the 6.8 release candidate running (on i386 and
amd64) last year at p2k7.

I mostly fixed it, but with some really crude hacks, and there's
still stuff from the initial .hc and .hi stage1 build kreeping into
stage2 and stage3. I suspect this can also happen for "normal"
builds (the libraries either aren't rebuilt at all or rebuilt
in-place).
And since ghc-6.10 will be released this year, I guess I have to
work on ghc-HEAD, because there's no chance to get any diff for 6.8
committed upstream.

No, the GHC build system already nothing more than a huge pile of
workarounds. I'm not willing to add yet another workaround.
The only alternatives to bootstrapping from .hc files are:
- maintain two versions of ghc in the tree (6.6, which is the last
bootstrappable version, and 6.8 or the upcoming 6.10),
- write a Haskell compiler (in C) that implements all the extensions to
the Haskell language that GHC needs to build.
Ciao,
