There never was a limit for 2GB.  4GB is no problem and more than 4GB
works fine also except if there are 32-bit PCI devices that do DMA (or
the machine has huge holes in the physical address space, which isn't
true for the prototypes).  For the DMA issue, a solution is in the
works (Goutham has been working on this).
