First, I want to warn not to try Gentoo installer. Neither Dialog vesion, nor GTK one. Though I managed to install Gentoo using GTK installer of 2007.0 LiveCD once, a LiveDVD never succeed (so, IMHO, downloading a LiveDVD is a waste of time and traffic).
But, that is not you should be afraid of. I find that installation from stage3 is much fun, so I encourage installing Gentoo linux in a true gentoo-way - from a stage3 tarball.
Handbook http://www.gentoo.org/doc/en/handbook/index.xml is more than enough to setup linux step-by-step.
I used a 2007.0 LiveDVD to boot, a stage3-i686 (x86) tarball from LiveDVD, and a recent portage snapshot (dated 13.09.2007, of course, now obsolete) from a Gentoo mirror.
Note: i found pci=nomsi kernel option of no use. I guess, that was thanks to a recent BIOS (02.09.2007 version, or something close).
My HDD partition scheme. Root, swap and windows correspondely. Not so smart, as it could be.
Note: Toggle measurement units in fdisk with 'u change display/entry units'. This will allow to partition nearly 100% of HDD space, still having few sectors unpartitioned
Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000080
Device Boot Start End Blocks Id System
/dev/sda1 1 8965 72011331 83 Linux
/dev/sda2 8966 9153 1510110 82 Linux swap / Solaris
/dev/sda3 * 9154 9730 4629271+ 7 HPFS/NTFS
Partition 3 does not end on cylinder boundary.
make.conf optimizations aren't finished yet. Anyway, you may download this one and use it as a base.
After reading Gentoo wiki article and comments to it and finally AMD forum I came to CFLAGS="-O3 -msse3 -march=k8 -pipe"
I'm using default Gentoo profile 'default-linux/x86/2007.0', an clean one, not 'default-linux/x86/2007.0/desktop'.
This allows controlling most of USE flags. Some are listed at make.conf, other - at /etc/portage/package.use
You may want to create your own package.use file and fill it, as necessary. Or download mine.
Kernel configuration was made using this as a sample.
NTFS support now is obsolete, as ntfs3g driver offers full write support. As far as FUSE module is needed, you may compile it into kernel or let ntfs3g build it while emerging.
Instead of emerging dhcpcd I recommend emerge [b]net-misc/dhcp[b]
DHCP client if this package more flexible, and allows receiving ms-classless-static-routes.
