Linux can have a small memory foot print. As far as I know, much of the size of a kernel image comes from statically compiled modules. If space is a concern, it's perfectly feasible to omit many kernel modules from the build process and only keep those required as modules.

I could bet the farm that's ECLipz , is code name for hardware emulation at the micro/milli code level. The new architecture could be framed like the CELL expecting one or more 390 CPU's married to a network of CELL processors , which in turn is supported by several other RISC processors to handle the various workloads and emulation. The major task of instruction decoding, and memory fetching can be done by another processor on behalf of the 390 CPU. That is a BIG portion of the heavy lifting required to execute a program. That's a lot of machine cycles saved, that's why RISC CPU's can boast they don't have those performance penalties to contend with, since it's somewhat separated out of the normal decoding behavior. Some 12 years ago,I initially believed the Linux having such a small kernel in it's early life had a distinct advantage of other OS's, but I was incorrect (and somewhat naive and misinformed) on how it would have performed on RISC versus the INTEL (386/486) implementations. The numbers do bear that out but I don't have much of an interest in that area any more since I back working exclusively with mainframes. I'm still a UNIX hobbyist and run both AIX and Linux at home, utterly frustrating and fun at the same time. If anyone out there know(Z) please tell me I'm still curious about where this is all going. Be A RISC based line of 390 CPU's or POWER like CPU with a 390 emulation.
