Unortunately this semms to prove what some forums said: Lenovo actually
delivers a BIOS that disables the hardware's PAE capabilities. (as
opposed to some Dell machines with the same electronics)

As of the discussion who steels RAM, the only hardware doing so could be
an onboard GPU using shared main memory.

I guess you have tried a BIOS upgrade? (sorry if I missed that in the
discussion)

To use all 4 Gigs, a 64bit kernel/distro should help, for testing
puposes a live CD pervents you from forced reinstallation.
