You think those are from kernel code? Hm, quite possible - some filesystem
code was the first that forced me to add the 060 trap handlers to the mostly
68040 kernel back then :-)
And - if you build a kernel with options M68060, it will be optimized
for 68060 - don't mess with the compiler options yourself unless
you have read the Makefiles etc. and really know what you're doing.
See the mailing list archives, think assembler code, etc.
