Yeah, reusing "bootm" may be too clever.

What I had in mind for overloading bootm is to do strncmp() operations 
for each of the subcommands (and where none of the subcommands could be 
interpreted as hex numbers - i.e. have a letter g-z or "_" in it) and, 
if none of the valid subcommands passed, do a legacy implementation 
where the three parameters are parsed as hex (or "-" for the ramdisk).

Again, while I like the concept of using "bootm" since we are familiar 
with it (and I don't have a better name), I would not be adverse to 
using a different command name since the New Improved "bootm" will be 
substantially different than bootm-classic.
