Like the previous tegra SOCs it's a ARMv7 instruction set core: the slackware userland will run fine on it.
The slackware tegra kernel might not boot on this board, as it was meant for a tegra2 SOC and did not support the GPU on that SOC anyway, so if you are not concerned about using a display on it I guess you could compile a vanilla kernel for the board and use the serial console to complete the installation.
I've no idea about support for the GPU as I've never had anything with nvidia's kepler GPU technology but I suspect that like most ARM SOC's the grafix drivers never make it into the mainstream kernel, famebuffer support is all that you are likely to ever get working.
Nvidia has a new Linux For Tegra kit with support for the new TK1 SOC that should allow manipulation of the internal flash on the TK1 board.
If it's true that each core performs 40% better then equivalent A9 core on the TEGRA2 ... the quad core 2.3Ghz should provide tons of power.
If I'm wrong about the grafix drivers I might even get one of these for an all use home desktop system that would use only a fraction of the power an Intel machine would require.
