Re: [Qemu-devel] qemu X3100 project

["René Rebe" <rene@exactcode.de>]

Hi Vincent,

did you continue on this great undertaking? Maybe you have a new version
of the patch already implementing some more bits?

I specifically ask if you have a new version to avoid duplicate work, as I
consider getting into this to get smoother graphic for my Qemu VM
instances :-)

Yours,
  René
