I did a OSkit-based kernel some time ago. But this was only a weekend
projekt. (It took longer to compile OSKit than to do anything else...)

I've put the stuff at

(I really should rename this...)

the diskimage can be written to a 1.44MB floppy with 
ftp://ftp.ira.uka.de/pub/squeak/demo/rawrite2.exe and the thing should
boot on a intel-PC.

The Squeak used is Paul Fernaut's embedded Squeak 2.2 (which had a simple
command-line interface). 

OSKit seems to be really nice... you can tailor the kernel just as you
need it, the squeak-kernel uses a very minimal configuration, it's more
like a boot-loader (no Virtual Memory, no Filesystem, not even a scheduler).

But all things needed for a real powefull OS are there: Filesystems,
Networking, Display, Threads, ... and you can simply link with Linux or 
FreeBSD drivers.
