The FCC doesn't place a restriction on how fast your modem can go. They do, however, place restrictions on power due to interference reasons. Increased frequency, by itself, doesn't mean more power -- think about the frequency of visible light and how much power it has (not much). It just so happens that no one has yet designed a narrow-band modem to run faster than 56K (only LU to my knowledge), and the others less than that despite advertising. From a theoretical perspective, the fastest attainable speed a narrow-band modem can reach on the existing phone systems is 64K -- that's how fast the line is sampled. Due to filtering and stuff, the 56K modems can only approach this.
