Stefan Reinauer 84e4bf69c7 interesting behavior, i thought svn could do moves.
the result should be ok though..

the purpose is dropping the old i82801er southbridge code
and using the ich5r code instead because its the same chip
but the code looks more solid and is used by many more systems.

Some of the old i82801er features have been ported (like hpet enable)
