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.
