Harry,
   I got a few minutes this morning to finish the new Virtualbox VM
test install of Gentoo. It worked fine for me.

   If you need any info about this let me know. Here's the main
points, the biggest being the use of DEVTMPFS in the kernel.

   If you want the actual kernel config file get in touch off list.

Cheers,
Mark

   Notes:

1) I chose the PCNET-OCI II NIC and set it as bridged. 4 processors, 2GB memory

2) /etc/fstab:
tux-test ~ # cat /etc/fstab
/dev/sda1               /boot           ext2            noauto,noatime  1 2
/dev/sda3               /               ext3            noatime         0 1
/dev/sda2               none            swap            sw              0 0
/dev/cdrom              /mnt/cdrom      auto            noauto,ro       0 0
tux-test ~ #

3) I added DEVTMPFS to the kernel config to get around the missing
/dev stuff in the current tarballs:

tux-test ~ # cat /usr/src/linux/.config | grep CONFIG_DEVTMPFS
CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y
tux-test ~ #

4) Interestingly, it boots even though I didn't add udev to sysinit:

tux-test ~ # rc-update show | sort
                 fsck |          boot
                 mtab |          boot
                 root |          boot
                 sshd |                       default
                 swap |          boot
                devfs |               sysinit
                dmesg |               sysinit
                local |                       default
               net.lo |          boot
               procfs |          boot
               sysctl |          boot
              hwclock |          boot
              keymaps |          boot
              modules |          boot
              urandom |          boot
             bootmisc |          boot
             hostname |          boot
             mount-ro | shutdown
             net.eth0 |                       default
             netmount |                       default
            killprocs | shutdown
            savecache | shutdown
            syslog-ng |                       default
           localmount |          boot
           vixie-cron |                       default
         termencoding |          boot
       udev-postmount |                       default
tux-test ~ #

5) World file:

tux-test ~ # cat /var/lib/portage/world
app-admin/logrotate
app-admin/syslog-ng
app-portage/eix
sys-apps/mlocate
sys-apps/pciutils
sys-boot/grub-static
sys-kernel/gentoo-sources
sys-process/vixie-cron
tux-test ~ #

6) /etc/make.conf file which I stole from another machine. Some USE
flags do not make sense in this context but they didn't hurt the
build.

tux-test ~ # cat /etc/make.conf
