This is how I do it:
I have a directory named after the kernel version 
("/usr/src/linux-2.4.19") and a link to this dir. ("/usr/src/linux -> 
/usr/src/linux-2.4.19").
So if any make or config script is looking for the kernel sources, 
there's always the link to the ones from the used kernel (if you update 
the link, after making a new kernel!).
Another tip from the author of cdrecord is, to rename the directories 
scsi, linux, asm in /usr/include/ (ex: /usr/include/asm.old) and make 
links to /usr/src/linux/include/asm/ (is normaly a link, generated by 
teh first make config or make xconfig etc.), 
/usr/src/linux/include/scsi/ and /usr/src/linux/include/linux/. I never 
had problems doing so, but I don't know if this is really save, the idea 
is that all scripts (make ...) will link against your used kernel.

You boot with the kernel in the mac system folder (by the way: only if 
you are using bootx on an oldworld mac, otherwise you don't need a 
kernel in you system folder).
