My setup is as follows
1. XP partion (ntfs)
2. linux partitions (/ and swap)
3. a fat32 partition for all of data from both oses as well as those programs that do not 
need registry crap

I use mozilla and have my local folder in the fat partiton. Works well for most things... 
Booksmarks and address books are not shared but htat is easy enough to correct.
