O.k., it's kern_slaballoc.c that's choking; if I compile it without
-march=pentiumpro, the kernel booted again.
$ cd /usr/src
$ KERNCONF=GZL:gcc2; CCVER=gcc2; __MAKE_CONF=/dev/null
$ export KERNCONF CCVER __MAKE_CONF
$ rm -rf $(make -V .OBJDIR)/sys/$KERNCONF
$ make buildkernel
$ cd $(make -V .OBJDIR)/sys/$KERNCONF
$ rm kern_slaballoc.o
$ make NO_CPU_COPT_FLAGS=yes

I'm not sure how to fix this, but I have to have some sleep now.
