Do I need to be concerned about (kernel is gentoo-sources:3.17.8-r1)?

Not really, it's business as usual with the intel drivers...

It should keep running if you ignore the error, but it might be stuck in software rendering mode afterwards. Only a reboot will fix that.

If it happens with kernel 3.18 too, reporting a bug as suggested by dmesg would be a good idea.
