My hack was even simpler!!  I just hacked the function guess_fsb to 
always return 133!!  (the kernel nor code is going nowhere other than 
this small eden box, so it matters not)...

My DMESG now shows:

longhaul: VIA C3 'Ezra' [C5C] CPU detected. Longhaul v2 supported.
longhaul: MinMult=5.0x MaxMult=6.0x
longhaul: FSB: 133MHz Lowestspeed=665MHz Highestspeed=798MHz


Thanks all for the pointers...
