Hello Ed and others,

Nice for the update. I will proceed with enabling this and provide you 
guys with a patch. I will
be working on another project for the next two weeks so do not expect it 

The last remaining items would be the VGA output. Do you see any 
problems in your port that
would prevent to use an external GFX card? I've been able to use the DMA 
engine part of our
PMC cards so I believe the PCIe itself is trained correctly.

We are using a PMC<->PCIe adapter and these cards operate 100%. That 
makes the VGA
issues even weirder, doesn't it?

Have you tried to use the G550 GFX shipped along with the Truxton dev 
kit? Did it work?

Thank you!
