Hmm, I'm not so sure.  Fedora uses a default of 500 MB to facilitate using preupgrade to upgrade to future releases.  While preupgrade is not likely to land in SL6, you never know what the future holds, and I don't think another 400 MB will cause hardship with today's storage devices.

Check /etc/yum.conf installonly_limit= and make sure you have enough space to support N kernels (5 is the default).  Looks like the baseline (grub, efi) + one kernel including kdump.img uses 52 MB on /boot; adding another kernel is 74 MB (+22 MB), but it didn't make another kdump kernel (4.3 MB).

So extrapolating that, five kernels would require a minimum of 162 MB, so I'd say 200MB is the minimum for /boot for a functional "out of the box" install.  Of course you could tweak down installonly_limit.

A quick google -- upstream says "For most users, a 250 MB boot partition is sufficient":  <http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/s2-diskpartrecommend-x86.html>
