Compaq had some "in house standard" for GART pages implementation.
You can find references to this in some third party chipset documentaiton.
This means they had a few bitfields where a generic GART driver could
retrive some information, e.g. if its a two level GART implementation.
I really dont know what sort of chip you do have. Do you have
the PCI IDs (including subvendor/device IDs) handy and possibly
a dump of the brige registers? Maybe its just a third party
ASIC development that was renamed for integration into the compaq
systems. If it is a GART capable chipset then it narrows down
to just a few vendors. Further hints on model name or a possible
windows module for GART support would be of great help in the end.

PS: i dont mention AGP at all because GART is the thing that
always was implemented vendor proprietary - its not a standard!
AGP support is highly generic, GART support is not.
