The compile and installation procedure worked without a failure. What
are these "artifacts" for and why are they not removed by the make
script?

Did you ever get a answer from Linus?

I did so before compiling - make clean after installing the kernel in
the boot directory would not affect my system?

Alec sent me a message to look into /var/log/dmesg. The messages are
indeed there but differ from var/log/messages by displaying only the
kernel related stuff. /var/log/messages additionaly seems to include
the startup messages.
One question related to kernel compiling: I tried "make zdisk" in
mounting the floppy before compiling and the second time only
inserting the floppy into the slot. After make zdisk linux refused to
accept the floppy and trying a floppy-boot resulted in a periodicaly
printed hex table on screen with the device sounding like a mashine
gun!
How can I mount this disk to reformat?
