This morning it struck me that what it reports is correct! It *does* have 
that amount of video memory available (aprox.) ONLY its part of PCI card's 
and not part of the main memory and thus the assertion that if there is no 
VRAM its part of DRAM0 is false.

Either the memory and I/O extents enumeration needs to be thought about PCI 
extents (PRM!) or the presence of a PCI SWI needs to be checked (using 
OS_SWINumberFromString) and if its there, then set a flag to indicate VRAM 
is NOT part of main memory.

Has Iyonix now support for its video now etc? the TODO is quite old and 
might not be relevant anymore.

With regards,
