Ivy Bridge and Xorg 7.7 on i386 FreeBSD 9-1BETA: no hardware acceleration?

I've hit this problem via installing PCBSD 9.1 RC2 albeit amd64 not 
i386. I couldn't even get VESA mode to work. Similar platform: Dell 15R 
SE 7520 with i7-3612QM including integrated Intel HD 4000 (GT2) and 
Radeon 7730M.

XAA acceleration was awful in that it produced approximately 5 second 
lag on some events like:

swapping desktops
bring new window to front
repainting a part of window previously obscured by another window
expanding drop-down menus (e.g. <SELECT> tags)
and more...

With some effort I do have a good, working desktop environment now.

I've updated to:

Mesa 8.0.4 (libGL, dri, libGLU, libGLw)
xf86-video-intel 2.20.12

This allowed me to use SNA acceleration which works lovely.

I did need to modify the above for FreeBSD though. I can supply patches 
if anyone is interested?

I'm writing this here in case it helps anyone and also to alert the port 
maintainers in case they want to bump the versions.

It does seem like the versions I'm using are way ahead of what's even 
being tested for Xorg 7.7 and there's the sticky issues about jumping up 
the Mesa 8.x.x and WITH_NEW_XORG flag. Maybe I didn't need to upgrade so 
far. I could try downgrading if that's of any use to anyone?

Let me know if I can be of any use!

Best regards,
