My install does not boot after hard reboot (ext3 broke)

[Elv13]

Hi, my computer gone crazy for apparently no reason when I was writing a text and with suddent rise from 0 to 100% cpu, disk write and ram, gentoo became quickly frozen. I had no choice but to do an hard reboot. But it broke ext3 and the journal fail to do his job. At that time, gentoo was booting fine, but USB was broken (no mouse and keyboard, only the emergency ps2 keyboard that is connected just in case). I rebboted on Ubuntu and did a fsck to reapair the disk, but after that, /bin was missing! Really funny... So I copied the /bin/bash binary from Ubuntu live cd and did a chroot. In the chroot, I emerged portage (portage was not broken apparently), emerged baselayout and did emerge --deep world + ctrl+c + while [ 1 ]; do emerge --deep world --resume --skipfirst; done .

10 hours layer, my 1200 packages were all rebuilded (2 error on java things, I dont care about those), quad core @3.2ghz rock . Then I tried to boot, but it didn't, only the kernel (that I had rebuilded too) started. It did also mount root, but fail to load rc/init. Why does those package still broken/inexistent? Arent they suppose to be restored after a succefull emerge -e world?

How can I fix this?

EDIT: Ok, after some googling, I found that -combine in make.conf + core2 + gentoo + baselayout 2 are not good friends, so I emerged base layout without that. rc-update and rc are back and the system can boot to bash by itself. But:
-No USB
-No network
-No graphical term (xterm, aterm, konsole and gnome-term fail to open)

So after all this, none of the problem that forced me to do a emerge -e world are solved. What should I do? untar the gentoo 2008.0 archive, do a regenworld and then a emerge -ekav world? (I used -b, so bin package were created, can I use them? I also noticed that the boot prosess did a -lot- of warning about missing "net" for all network dependant package, but net.eth0 exist.

EDIT2: Ok, after doing a lot of ln -s, etc-update and env-update (and source /etc/profile), usb work again (i got a mouse!!!) but not net. I copied net.eth0 from 2008.0 stage 3 (the file was gone), but it did not help. The error is

Ok, so after playing a little with it again, I think that I found the problem. /sbin/functions.sh seem to contain a lot of gentoo specific boot/init functions, but it is not loaded by the newly upfated (at least on my install) baselayout (2.0.0), so init script cant find their env vars and functions, so they just fail. How can i prevent that?

EDIT: I masked baselayout2 and emerged baselayout1, it did fix all function.sh junk. It is not a bad idea to upgrade, if you get problem like mine, resore baselayout.
