915resolution on an i810

[Grant]

I'm getting the following when trying to run '915resolution -l' with
my i810 onboard video:

system1 ~ # 915resolution -l
Intel 800/900 Series VBIOS Hack : version 0.5.2
Intel chipset detected.  However, 915resolution was unable to
determine the chipset type.
Chipset Id: 71248086
Please report this problem to stomljen at yahoo.com

Is there anything I can do?  Could 915resolution work anyway?
