It should be fine as PC2100 *is* the 133MHz FSB rating.
You can get the FSB MHz by dividing the 'data rate' rating by 16.
2100/16=131.25, which is 133MHz FSB (because they rounded off the 2100).
PC2700 is 166 Mhz FSB, etc.
The 16 comes from the bus being 64 bit wide, which is 8 (8 bit) bytes.
Single data rate RAM, e.g. PC133, sends 8 bytes per cycle. DDR is double
data rate for 16 bytes per cycle. FSBx16=DDR bytes/sec.
