The size of that partition depends on firmware limitations. I have 
definitely seen reports of systems not booting when the PReP boot 
partition was too large. I think on some systems that has even happened 
at 8MB.

In other words, should you need more space than 4-5MB at some point in 
the future, you cannot simply make a bigger boot partition.
