35 gentoo-releng is not really a help list, so I have replied off list.
36 You need a later kernel than the one on the 2007.0 liveCD.
37 The current gentoo-sources is fine, then set you kernel configuration
38 as this post http://forums.gentoo.org/viewtopic-p-4570091.html#4570091

40 I wrote that in response to a Intel ICH7 question but it works for ICH6
41 chipsets and later. No patch is needed.
