Turns out XP is generally OK.  The reported problem was only on
specific configurations (some BIOS stuff).  Windows 2000 reportedly
would be hurt but I really think we don't have to care about that too
much.  So, it seems like we wouldn't have to worry too much about it
and just go ahead with new alignment schemes.  I'll update the doc
this weekend with new information from this now rather large thread.

Thanks.
