Some reasons you might have needed (or still do) boot partitions:

The first popular reason they were so common was because Hard Drives 
were larger than what the BIOS could address.  I forget if this was at 
2GB, 8GB, or possibly both.  In any case, Lilo: (the bootloader of the 
day) could only access hard drives and sectors directly addressable by 
the BIOS, so the kernel (hence boot partition) had to be placed at the 
start of the drive.

You would also use a boot partition if your root is on a Raid array 
(other than Raid 1 - mirror.)

You might think it's a good idea to have a boot parition if the rest of 
your system is on LVM, though I don't think that's mandatory anymore.
