I think we need to refocus on what would give the most benefit.  At least
as far as I can see:

- port/package management: most users would benefit
- improved virtualisation support: a lot of users would benefit
- improved driver support: a lot of users would benefit
- KMS/GEM for better graphics card support: a lot of users would benefit

Can you honestly say the same about handling line rate packet forwarding
for multiple 10G cards?

I suspect I would rank true multipath storage support above 10G routing,
for example.
