This won't be of much help to you, but I am using 7.10 64 bit version at the moment, installed on an old spare 20Gb HD.
20 mins after putting the CD in, I was on the internet with it all working - and the Office suite can show the new M$ 2007 Excel spreadsheets.
Have a look at the website - there seem to be quite a few versions of it.
I am getting quite into Ubuntu and its tempting to leave M$ altogether. Has a lot of nice screen savers on it!
