i don't know about the modem problem but i might be able to answer your question about the sound card dissappearing...
when you increase ur fsb that means that the pci bus is running out of spec too... even tho the sound card is built onto the mobo it still uses the pci bus... and when that becomes too high for the card to hand it dissappears...
just thoughts... can't say for sure tho...
