This seems like a silly hard code. Especially for a feature distros don't
care enough about to implement a working initrd for.

Has anyone bothered to justify those large amounts of memory?
Where does the 128M go?

Please pardon me for being a cynic but I don't see the command line option
being the bottleneck for real users to make this work.
