Don't worry about the max cpu compatible with a board, Intel CPUs are multiplier locked and thus will run at the correct speed as long as the mobo supportsa the correct fsb.
Now about Tualatin support, Tualatin Support can be determined by the chipset being used. The only Tualatin Capable chipsets are i815 B-Stepping, some stepping of i810e (cant think of the stepping), SiS 630T, and VIA 133T. So if your mobo has VIA 133A, then no, it wont support TUalatin without a Slotket/ or Socket 370 to Socket 370T adapter.
