You'll run into something similar regardless of the chipset. 32-bit PCI 
cards need MMIO below 4GB, so a chipset must provide a memory hole for them.
A "nice" chipset will allow you to remap the affected memory above 4GB, and 
a "nice" operating system will allow you to use that remapped memory.

If it's not on fire, it's a firmware problem.
