I'm inclined to agree with you about the FAT32 idea.  I've never liked
the idea particularly.  As for sharing your Linux partitions with
Windows using native Linux file systems - you could always use ext2.
The only difference between ext2 and ext3 is the latter is a journaling
file system.  Unless you really need the journal, you don't have to have
it; ext2 DOES allow your drives to go to sleep.

Until a few more file system drivers are ported to win32 (like xfs,
reiferfs, jfs, etc) your only alternatives in this situation are ext2 or
FAT32.  Obviously FAT32 isn't an option and ext3 will eat your battery
for breakfast.

Not that I know of.  I guess you could hack the ext3 kernel code, but
that's exceedingly ugly.
