X server in dom0: Bad VBT signature

[rudolf <netbsd%eq.cz@localhost>]

Hi,

I have some problems running X server from base in amd64 dom0 under 
netbsd-6. It's on a notebook with Intel GM45 Express chipset, the error 
message is "Bad VBT signature". I've tried the Xen versions 3.3 and 4.1 
from pkgsrc, the result is in both cases the same.

Is there a workaround or solution for this problem? I am able to 
experiment with the setup and test any prospective patches.

Thanks for any suggestions, attached is the X server log with the 
mentioned failure and dmesg from the notebook running almost GENERIC kernel.

Regards,

r.
