ext3 for grub is redundant, as the journal is so seldom used. The only 
real differene between ext2 and ext3 is that journal, which only ever 
comes into play if disk writes are interrupted and you only write 
to /boot if you update a kernel, or edit menu.lst. If the power goes 
off while you are executing 
cp /usr/src/linux/arch/i386/boot/vmlinuz /boot/[kernel-name]
you still have the old image to boot from. If disk corruption occurred 
and a journal can't help then you have serious problems way beyond 
the scope of a journal.

Your mistrust of grub is misplaced :-)
grub reads from and grub-install writes to /boot/grub/*. That will 
happen whether it's a separate partition or not. The entire original 
reason for a separate /boot was to guarantee that all of /boot would 
reside on cylinder numbers < 1024, due to BIOS restrictions. This 
hasn't been the case since the late 90's.

A separate /boot is still useful if you multi-boot several distros or 
frequently change distros and want to keep the old kernel images. 
Otherwise it's largely superfluous, especially on a workstation.
