Yes, Debian enables CONFIG_OLPC in its 486 kernel (and one of these days, I'll open up a bug for them to enable it in their 686 kernel). There are 3 types of touchpads in OLPC XO machines (hgpk, synaptics, and sentelics). If the hardware is either hgpk or sentelics, we want those extensions to load. If the hardware is synaptics, we want the extension not to load. Doing this via kernel arg doesn't work, as a generic distributions (and even those built specifically for OLPC XOs) will not know which touchpad hardware will be in use. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
