If /boot partition starts on the first cylinder, and if your drive 
reports 255 heads and 63 sectors per track, this will give you BIOS 
addressable range of aprox 8Gb (a little bit less):

255 heads * 63 cylinders * 512 bytes * 1024 cylinders

Anything above it, and your BIOS can't access it.

To answer your original question.  100 MB is more than enough for /boot 
if you are periodically cleaning old obsoleted kernels.
