HP 6730b - touchpad and keyboard only working when DMA disabled

[HonkXL]

I tried to use Haiku on a HP 6730b notebook. Works fine, but built in touchpad and keyboard are not working. External USB mouse and keyboard works fine!

I found out that the built in ones are only working, if I disable DMA on the startscreen of Haiku.

Output of listdev see below.

I already had exactly the same problem on a Fujitsu notebook, so I think it depends on the chipset or the graphics driver in any way.

If I set graphics driver to VESA, I can leave DMA enabled - mouse and touchpad are then working.

If you need more informations about the system, I will give them!
