That's it.
I hacked together a new timer.c based on freebios/src/pc80/udelay_timer2.c
You may want to offer it as an alternative, but then again, maybe not.
I can now boot linux using filo !
Thanks for all your help.

Maybe RDTSC causes invalid opcode exception, and since there is no
exception handler, the CPU resets.
filo/i386/timer.c must be re-written to support pre-Pentium CPUs.
