minimium requirement of intel graphics software stack for hd4400

i was using slackware 12.2 32bit, now i am trying to cross-compile to x86_64,

then upgrade xorg packages to 14.0, in ordr to bring up intel hd4400 graphics

i have compiled all base packages, plus xorg, xfce, to x86_64, base packages work well,

but xorg, i can only use vesa or fb driver, not intel. besides, the resoluton is 1280x1024 at most,

and my box is a yoga pro 2, which is i7-4510, 8G ram, 3200x1800 lcd.

so i guess i have to install at least 2013q1 intel graphics stack. is that so?

hope you guys know what i meant.
