Don't use these options, 686 implies SSE/MMX stuff.

Features=0x383fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,_*SSE*_>

FreeBSD already identifies it, or it could be because of your options 
but I think not.

options CPU_FASTER_5X86_FPU is for  Cryix 5x86

http://people.freebsd.org/~kato/cpuident.html

Also how does your /etc/make.conf look?

Have you tried ln -s aj /etc/malloc.conf, or something like this.  It is 
in the archives under current if you search for it.

$ sysctl -da | grep machdep.dis
machdep.disable_rtc_set:
machdep.disable_mtrrs: Disable i686 MTRRs.   <<==very bad for 
performance, most likely here because of some bad cyrix options you 
have.  Those are for a 586(I think 586) class cpu
