I'm skeptical. Why would a modem use physical system RAM? Why would a
sound card use physical system RAM? 

More-importantly, why did this design change? 

MY T42p has none of these problems, and sees the full 4GB of RAM, runs a
32-bit OS, and has an integrated graphics adapter. 

Now that I've "upgraded" to an Intel Core 2 Duo, discrete (external)
graphics, etc. I lose 25% of my physical RAM. I may sell these two
laptops and go back to my T42p if I can't solve this.
