I've gone through the 2.6.36 config. It's indeed overflowing with
exotic options, some of which I have never even read the description
for. I've gone through them, but let's keep their pruning on the
programme in case tackling anything else doesn't lead anywhere.

As for the common config options, I too suggest removing initramfs
completely. The target CPU is set as a generic 64b. Judging by your
`emerge --info`, you probably have a Pentium 4. The config will also
start SELinux by default. God knows I'm not proficient with SELinux,
but I suppose it requires extended attributes support in the
filesystem. Ext_attr is enabled for ext3 (you /boot), but disabled for
reiserfs, which in turn seems to be on your /, judging by the fstab. At
any rate, removing SELinux out of the kernel completely will be far from
harmful (unless you know you need it and actually use it for something
specific, of course). ATA-related options seem to be OK. The /dev nodes
should be called sda*.

Your `emerge --info` implies that the system isn't all that old. That's
very good. I think it's well possible to run at least an 'emerge -uD
world' on the system without messing it up irreversibly. That's one big
(albeit somewhat off-topic) suggestion, in case you're not switching to
another distro really soon.

I can also imagine some highly unlikely, yet possible collision between
the relatively recent in-kernel ext3/reiserfs drivers and the old
userland. If it doesn't cause an avalanche of updates, try emerging the
latest stable udev, e2fsprogs, reiserfsprogs and perhaps also
util-linux and baselayout. Just to be sure. Don't rely on dependencies
absolutely (such as in case of the intended udev semi-update).

Another unlikely, but possible problem: long-forgotten custom udev rules
that are in some way incompatible with something new. Of course, this
may / may not apply depending on how far you get during the boot-up.

So far for the first-hand stuff. Let's wait here for your updates on the
latest events.
