A commit hit Haiku Git today entitled Add support for my Core i3 integrated graphics. The commit just adds Haswell desktop PCI IDs and that's about it, but was apparently enough to have Adrien Destugues' Core i3 Haswell system now light up with Haiku.
The ID was 0x0412 which matches for Haswell desktop GT2 graphics.
Haiku still has a ways to go with its graphics support, but at least mode-setting will hopefully work if you have compatible Haswell HD Graphics but don't expect much more beyond mode-setting... Even for popular BSD distributions that are better manned they have a challenging time with open-source graphics driver support ported over from Linux. Just earlier this month is when DragonflyBSD got working Haswell graphics
