[CentOS] Intel 4600 Graphics (Haswell) in CentOS 6.4

Quick question that I haven't been able to find the answer to (and not for
lack of trying, believe me): Is dual-monitor display for the new Intel HD
Graphics 4600 (Haswell, e.g. Intel E3-1200v3 family processors) supported
in CentOS 6.4? In particular, I'm looking at a SuperMicro X10SAE;
SuperMicro has already replied that triple-display only works with a
VGA-HDMI-DP combo (lame) and only in Windows (lame), but had no information
as to dual-display (they reported to me that only tested single-head
configurations [lame] before marking it as "supported" on their website).

I already found that the Intel opensource site only has releases for Fedora
19 and Ubuntu 13, and that X.org lists the latest release as 2011Q3 and the
latest support as SandyBridge:
http://01.org/linuxgraphics/downloads
http://www.x.org/wiki/IntelGraphicsDriver/
But the latest version of xorg-x11-drv-intel in ElRepo Extras was uploaded
in March of this year, and I haven't found whether the upstream vendor
backported or sideported something into the latest distribution.

[Yes, I'm STILL working on the workstation configuration. We're considering
putting off triple-head support to cut costs, because the dreamy NVS510
cards are expensive. It's like a morass of quicksand sometimes.]

Gracias y saludos,
