The pre-built iso only works on certain AMD (Brazos) chipsets. You'll have to do your own build for Intel, and there's a LOT of pieces that are not working right now.
All that said, I've been running the Honeycomb RC2 x86 build on my Azpen (Tegra 2) tablet in a dual-boot config with Windows 8 for several weeks now. Overall pretty stable. I'm looking forward to the ICS build. Certainly a lot of potential.
