Yes. Not many use VIA cpu's, so I think it would help a lot if you'd do a 
send-pr. Include a full dmesg so the CPU flags can be seen. The default on 
FreeBSD is to compile with -O2 now, so either cc should disable the specific 
optimization for which there is no matching CPU instruction internally, or 
via CPUTYPE or similar constructs, the optimization flag for this should be 
turned off.
-O2 is a collection of optimizations that can be turned on/off 
individually. -O = -O1 is a smaller set, -O0 turns it off entirely.
