freebsd 6.1rc2 lacks i945 agp support

I have a Dell Optiplex 520 using i945 (ICH7) chipset.

I have device agp in my kernel but /dev/agpgart is not being setup. This then 
effects the opertion of Xorg 6.9.x by not allowing it to load DRI and thus no 
XVideo support.

Could someone please help to sort this out. There have been several emails to 
various lists but absolutely no support given what so ever..

Who maintains agp_i810.c ? Could we please get some input on this. Several 
others have emailed to various lists also enquiring about this exact problem 
only also to be unanswered.

Reference to supporting errors and pciconf output can be found here

Please get back to me and I can provide whatever files/output/conf's are 
needed to resolve this.

Please help!
