All 32 bit OSs have this limitation.  Specifically the total addressable
about of memory is 4 GiB, but this includes memory that may be on your
GPU (which on some machines gets counted twice), as well as CPU cache.
There are ways around this, but the best method is to simply use the 64
bit variant.

I can also say that the RT kernel in 9.04 works just fine with my dual
core machine.
