Kernel Compile which is better modules or in the kernel

[1stFlight !]

 Hey I'm getting ready to compile yet another kernel then it hits me,
why are some things compiled as modules and others into the kernel? If
I'm running  a box with 128MB of ram does it really matter how large my
kernel gets? How about if I've only got 32MB ?  Is it faster to have
some things run in the kernel? Please advise...thanks!
