Good idea, but we should make this a bit more comfortable and intelligent.

Here my 2 cents:

** parameter in /etc/sysconfig/config:
CONFIG_RAMDISK_SIZE=auto | size in MB
So you could specify the maximum size manually or use our script to 
calculate it.
Per default it should be set to "auto".

** more intelligent
The script should also take care about swap space, but should print out 
a warning when he thinks that the system will start swapping.
With this warning, the user would know that he looses performance but 
the system will still function as expected

** RAM usage of programs
We don't only need the size of the programs, we would also need to know 
their ram usage when the program is running.
But I think that's a bit hard, because it really depends on the 
environment and what the user is doing.
